Name: libhogweed6 Distribution: SUSE Linux Enterprise 15
Version: 3.9.1 Vendor: SUSE LLC <>
Release: 150600.1.46 Build date: Sat May 18 21:07:59 2024
Group: System/Libraries Build host: h04-ch1b
Size: 357970 Source RPM: libnettle-3.9.1-150600.1.46.src.rpm
Summary: Cryptographic Library for Public Key Algorithms
Nettle is a cryptographic library that is designed to fit easily in more or
less any context: In crypto toolkits for object-oriented languages (C++,
Python, Pike, ...), in applications like LSH or GNUPG, or even in kernel space.

The libhogweed library contains public key algorithms to use with libnettle.






* Fri Jun 09 2023
  - Add the architecture specific READMEs as provided by upstream.
* Thu Jun 08 2023
  - Include the nettle library manual in HTML and PDF formats in
    the devel package.
* Wed Jun 07 2023
  - update to 3.9.1: [bsc#1212112, CVE-2023-36660]
    * Fix bug in the new OCB code may be exploitable for denial of
      service or worse due to memory corruption
* Mon May 15 2023
  - update to 3.9
    * rewrite of the C and plain x86_64 assembly implementations of
      GHASH to use precomputed tables in a different way, with tables
      always accessed in the same sequential manner. This should make
      Nettle's GHASH implementation side-channel silent on all
      platforms, but considerably slower on platforms without carry-
      less mul instructions. E.g., benchmarks of the C implementation
      on x86_64 showed a slowdown of 3 times.
    * Fix bug in ecdsa and gostdsa signature verify operation, for
      the unlikely corner case that point addition really is point
    * Fix for chacha on Power7, nettle's assembly used an instruction
      only available on later processors
    * Add support for the SM4 block cipher
    * Add support for the Balloon password hash
    * Add support for SIV-GCM authenticated encryption mode
    * Add support for OCB authenticated encryption mode.
    * New exported functions md5_compress, sha1_compress,
      sha256_compress, sha512_compress
    * multiple performance optimizations
    * Delete all arcfour assembly code. Affects 32-bit x86, 32-bit
      and 64-bit sparc
* Wed Mar 08 2023
  - Build AVX2 enabled hwcaps library for x86_64-v3
* Thu Jul 28 2022
  - update to 3.8.1:
    * Avoid non-posix m4 argument references in the chacha
      implementation for arm64, powerpc64 and s390x. Reported by
      Christian Weisgerber, fix contributed by Mamone Tarsha.
    * Use explicit .machine pseudo-ops where needed in s390x
      assembly files. Bug report by Andreas K. Huettel, fix
      contributed by Mamone Tarsha.
* Mon Jul 11 2022
  - update to 3.8:
    This release includes a couple of new features, and many
    performance improvements. It adds assembly code for two more
    architectures: ARM64 and S390x.
    The new version is intended to be fully source and binary
    compatible with Nettle-3.6. The shared library names are and, with sonames and
    New features:
    * AES keywrap (RFC 3394), contributed by Nicolas Mora.
    * SM3 hash function, contributed by Tianjia Zhang.
    * New functions cbc_aes128_encrypt, cbc_aes192_encrypt,
      On processors where AES is fast enough, e.g., x86_64 with
      aesni instructions, the overhead of using Nettle's general
      cbc_encrypt can be significant. The new functions can be
      implemented in assembly, to do multiple blocks with reduced
      per-block overhead.
      Note that there's no corresponding new decrypt functions,
      since the general cbc_decrypt doesn't suffer from the same
      performance problem.
    Bug fixes:
    * Fix fat builds for x86_64 windows, these appear to never
      have worked.
    * New ARM64 implementation of AES, GCM, Chacha, SHA1 and
      SHA256, for processors supporting crypto extensions. Great
      speedups, and fat builds are supported. Contributed by
      Mamone Tarsha.
    * New s390x implementation of AES, GCM, Chacha, memxor, SHA1,
      SHA256, SHA512 and SHA3. Great speedups, and fat builds are
      supported. Contributed by Mamone Tarsha.
    * New PPC64 assembly for ecc modulo/redc operations,
      contributed by Amitay Isaacs, Martin Schwenke and Alastair
    * The x86_64 AES implementation using aesni instructions has
      been reorganized with one separate function per key size,
      each interleaving the processing of two blocks at a time
      (when the caller processes multiple blocks with each call).
      This gives a modest performance improvement on some
    * Rewritten and faster x86_64 poly1305 assembly.

* Wed Jun 09 2021
  - GNU Nettle 3.7.3: [CVE-2021-3580, bsc#1187060]
    * Fix crash for zero input to rsa_sec_decrypt and
      rsa_decrypt_tr. Potential denial of service vector.
    * Ensure that all of rsa_decrypt_tr and rsa_sec_decrypt return
      failure for out of range inputs, instead of either crashing,
      or silently reducing input modulo n. Potential denial of
      service vector.
    * Ensure that rsa_decrypt returns failure for out of range
      inputs, instead of silently reducing input modulo n.
    * Ensure that rsa_sec_decrypt returns failure if the message
      size is too large for the given key. Unlike the other bugs,
      this would typically be triggered by invalid local
      configuration, rather than by processing untrusted remote
* Sun Mar 21 2021
  - GNU Nettle 3.7.2:
    * fix a bug in ECDSA signature verification that could lead to a
      denial of service attack (via an assertion failure) or possibly
      incorrect results (CVE-2021-20305, boo#1184401)
    * fix a few related problems where scalars are required to be
      canonically reduced modulo the ECC group order, but in fact may
      be slightly larger
* Thu Feb 18 2021
  - GNU Nettle 3.7.1:
    * Fix bug in chacha counter update logic (ppc64 and ppc64el)

  - GNU Nettle 3.6:
    * removal of internal and undocumented poly1305 functions
    * Support for Curve448 and ED448 signatures
    * Support for SHAKE256, SIV-CMAC, CMAC64, "CryptoPro" variant of
      the GOST hash (as gosthash94cp), GOST DSA signatures, including
      GOST curves gc256b and gc512a
    * Support for Intel CET in x86 and x86_64 assembly files, if
      enabled via CFLAGS (gcc --fcf-protection=full)
    * A few new functions to improve support for the Chacha
      variant with 96-bit nonce and 32-bit block counter (the
      existing functions use nonce and counter of 64-bit each),
      and functions to set the counter.
    * New interface, struct nettle_mac, for MAC (message
      authentication code) algorithms. This abstraction is only
      for MACs that don't require a per-message nonce. For HMAC,
      the key size is fixed, and equal the digest size of the
      underlying hash function
    * multiple bug fixes
  - drop nettle-respect-cflags.patch
  - silence packaging warning raised by HMAC files
    (bsc#1152692, jsc#SLE-9518)

    required when running in FIPS mode (bsc#1152692, jsc#SLE-9518)
* Thu Aug 01 2019
  - update to 3.5.1:
    * correct upstream source packaging problems
  - new in 3.5:
    * gcm_crypt will now call the underlying block cipher to process
      more than one block at a time
    * Support for CFB8 (Cipher Feedback Mode, processing a single
      octet per block cipher operation)
    * Support for CMAC (RFC 4493)
    * Support for XTS mode
    * various improvements
* Wed Jan 02 2019
  - Update to 3.4.1 release
    * Fix CVE-2018-16869 (bsc#1118086)
      All functions using RSA private keys are now side-channel
      silent, meaning that they try hard to avoid any branches or
      memory accesses depending on secret data. This applies both to
      the bignum calculations, which now use GMP's mpn_sec_* family
      of functions, and the processing of PKCS#1 padding needed for
      RSA decryption.
    * Changes in behavior:
      The functions rsa_decrypt and rsa_decrypt_tr may now clobber
      all of the provided message buffer, independent of the
      actual message length. They are side-channel silent, in that
      branches and memory accesses don't depend on the validity or
      length of the message. Side-channel leakage from the
      caller's use of length and return value may still provide an
      oracle useable for a Bleichenbacher-style chosen ciphertext
      attack. Which is why the new function rsa_sec_decrypt is
    * New features:
      A new function rsa_sec_decrypt.
    * Bug fixes:
    - Fix bug in pkcs1-conv, missing break statements in the
      parsing of PEM input files.
    - Fix link error on the pss-mgf1-test test, affecting builds
      without public key support.
* Thu Dec 06 2018
  - Adjust SRPM group.
* Tue Dec 04 2018
  - libnettle 3.4.1rc1: [bsc#1118086, CVE-2018-16869]
    * pkcs1-decrypt.c (pkcs1_decrypt): Rewrite as a wrapper around
      _pkcs1_sec_decrypt_variable. Improves side-channel silence of the
      only caller, rsa_decrypt.
    * rsa-sec-compute-root.c (sec_mul, sec_mod_mul, sec_powm): New
      local helper functions, with their own itch functions.
      (_rsa_sec_compute_root_itch, _rsa_sec_compute_root): Rewrote to
      use helpers, for clarity.
    * rsa-decrypt-tr.c (rsa_decrypt_tr): Use NETTLE_OCTET_SIZE_TO_LIMB_SIZE.
    * rsa-sec-compute-root.c (_rsa_sec_compute_root): Avoid calls to
      mpz_sizeinbase, since that potentially leaks most significant bits
      of private key parameters a and b.
    * rsa-sign.c (rsa_compute_root) [!NETTLE_USE_MINI_GMP]: Use
    * testsuite/rsa-sec-compute-root-test.c: Add more tests for new

    * rsa-sign.c (rsa_private_key_prepare): Check that qn + cn >= pn,
      since that is required for one of the GMP calls in
    * rsa-decrypt-tr.c: Switch to use side-channel silent functions.
    * pkcs1-sec-decrypt.c (_pkcs1_sec_decrypt_variable): New private
      function. Variable size version for backwards compatibility.
    * testsuite/rsa-sec-decrypt-test.c: Adds more tests.
    * rsa-sec-decrypt.c (rsa_sec_decrypt): New function.
      Fixed length side-channel silent version of rsa-decrypt.
    * testsuite/rsa-encrypt-test.c: add tests for the new fucntion.
    * testsuite/pkcs1-sec-decrypt-test.c: Adds tests for _pkcs1_sec_decrypt.
    * gmp-glue.c (mpn_get_base256): New function.
    * pkcs1-sec-decrypt.c (_pkcs1_sec_decrypt): New private function.
      Fixed length side-channel silent version of pkcs1-decrypt.
    * cnd-memcpy.c (cnd_memcpy): New function.
    * testsuite/cnd-memcpy-test.c: New test case.
    * rsa-sign-tr.c (rsa_sec_compute_root_tr): New function that uses
      _rsa_sec_compute_root, as well as side-channel silent RSA blinding.
      (rsa_compute_root_tr) Rewritten as a wrapper around	rsa_sec_compute_root_tr.
      (rsa_sec_blind, rsa_sec_unblind, sec_equal, rsa_sec_check_root)
      (cnd_mpn_zero): New helper functions.
      (rsa_sec_compute_root_tr) [NETTLE_USE_MINI_GMP]: Defined as a not
      side-channel silent wrapper around rsa_compute_root_tr, and the
      latter function left unchanged.
    * rsa-sec-compute-root.c (_rsa_sec_compute_root_itch)
      (_rsa_sec_compute_root): New file, new private functions.
      Side-channel silent version of rsa_compute_root.
    * rsa-internal.h: New header file with declarations.
    * gmp-glue.h (NETTLE_OCTET_SIZE_TO_LIMB_SIZE): New macro.
    * tools/pkcs1-conv.c (convert_file): Add missing break statements.
    * nettle-internal.c (des_set_key_wrapper, des3_set_key_wrapper)
      (blowfish128_set_key_wrapper): Wrapper functions, to avoid cast
      between incompatible function types (which gcc-8 warns about).
      Wrappers are expected to compile to a single jmp instruction.
    * des-compat.c (des_compat_des3_decrypt): Change length argument type to size_t.
* Thu Feb 22 2018
  - Use %license (boo#1082318)
* Sun Nov 19 2017
  - libnettle 3.4:
    * Fixed an improper use of GMP mpn_mul, breaking curve2559 and
      eddsa on certain platforms
    * Fixed memory leak when handling invalid signatures in
      ecdsa_verify. Fix contributed by Nikos Mavrogiannopoulos.
    * Reorganized the way certain data items are made available:
      Nettle header files now define the symbols
      nettle_hashes, nettle_ciphers, and nettle_aeads, as
      preprocessor macros invoking a corresponding accessor
      function. For backwards ABI compatibility, the symbols are
      still present in the compiled libraries, and with the same
      sizes as in nettle-3.3.
    * Support for RSA-PSS signatures
    * Support for the HKDF key derivation function, defined by RFC
    * Support for the Cipher Feedback Mode (CFB)
    * New accessor functions: nettle_get_hashes,
      nettle_get_ciphers, nettle_get_aeads, nettle_get_secp_192r1,
      nettle_get_secp_224r1, nettle_get_secp_256r1,
      nettle_get_secp_384r1, nettle_get_secp_521r1.
      Direct access to data items is deprecated going forward.
    * The base16 and base64 functions now use the type char * for
      ascii data, rather than uint8_t *. This eliminates the last
      pointer-signedness warnings when building Nettle
    * The contents of the header file nettle/version.h is now
      architecture independent, except in --enable-mini-gmp
    * Prevent data sizes from leaking into the ABI
  - Fixes previously carried as patches:
    * Fix compilation error with --enable-fat om ARM
      Drop nettle-3.3-fix-fat-arm.patch

    * nettle-3.3-fix-fat-arm.patch
* Sun Sep 03 2017

* Thu Feb 09 2017
  - Explicitly BuildRequire m4
* Fri Oct 28 2016
  - libnettle 3.3:
    * Invalid private RSA keys, with an even modulo, are now
      rejected by rsa_private_key_prepare. (Earlier versions
      allowed such keys, even if results of using them were bogus).
      Nettle applications are required to call
      rsa_private_key_prepare and check the return value, before
      using any other RSA private key functions; failing to do so
      may result in crashes for invalid private keys.
    * Ignore bit 255 of the x coordinate of the input point to
      curve25519_mul, as required by RFC 7748. To differentiate at
      compile time, curve25519.h defines the constant
    * RSA and DSA now use side-channel silent modular
      exponentiation, to defend against attacks on the private key
      from evil processes sharing the same processor cache. This
      attack scenario is of particular relevance when running an
      HTTPS server on a virtual machine, where you don't know who
      you share the cache hardware with.

    * Fix sexp-conv crashes on invalid input
    * Fix out-of-bounds read in des_weak_p
    * Fix a couple of formally undefined shift operations
    * Fix compilation with c89
    * New function memeql_sec, for side-channel silent comparison
      of two memory areas.
    * Building the public key support of nettle now requires GMP
      version 5.0 or later (unless --enable-mini-gmp is used).

    * By accident, nettle-3.1 disabled the assembly code for the
      secp_224r1 and secp_521r1 elliptic curves on all x86_64
      configurations, making signature operations on those curves
      10%-30% slower. This code is now re-enabled.
    * The x86_64 assembly implementation of gcm hashing has been
      fixed to work with the Sun/Oracle assembler.
