* Remote crash in RSA decryption via manipulated ciphertext- Add patches:
* libnettle-CVE-2021-3580-rsa_sec.patch
* libnettle-CVE-2021-3580-rsa_decrypt.patch
* Wed Jun 09 2021 infoAATTpaolostivanin.com- 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 data.
* Mon Apr 19 2021 pmonrealAATTsuse.com- Security fix: [bsc#1184401, CVE-2021-20305]
* multiply function being called with out-of-range scalars

* 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 andreas.stiegerAATTgmx.de- GNU Nettle 3.7.1:
* Fix bug in chacha counter update logic (ppc64 and ppc64el)
* Restore support for big-endian ARM platforms

* various improvements
* Sun Mar 17 2019 jsikesAATTsuse.de- Update to 3.4.1 - FATE#327114 (bsc#1129598)
* Fix CVE-2018-16869 (bsc#1118086) libnettle-CVE-2018-16869-3.4.patch (removed) 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 recommended.
* 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 jengelhAATTinai.de- Adjust SRPM group.
* Tue Dec 04 2018 pmonrealgonzalezAATTsuse.com- 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 _rsa_sec_compute_root.
* testsuite/rsa-sec-compute-root-test.c: Add more tests for new side-channel silent functions.
* rsa-sign.c (rsa_private_key_prepare): Check that qn + cn >= pn, since that is required for one of the GMP calls in _rsa_sec_compute_root.
* 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 fvogtAATTsuse.com- Use %license (boo#1082318)
* Sun Nov 19 2017 astiegerAATTsuse.com- 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 5869
* 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
* Mon Sep 04 2017 asnAATTcryptomilk.org- Add patch to fix build of fat-arm:
* nettle-3.3-fix-fat-arm.patch
* Sun Sep 03 2017 asnAATTcryptomilk.org- Build nettle with AES-NI support (bsc#1056980)
* Thu Feb 09 2017 dimstarAATTopensuse.org- Explicitly BuildRequire m4
* Fri Oct 28 2016 astiegerAATTsuse.com- 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 NETTLE_CURVE25519_RFC7748.
* 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. bsc#991464 CVE-2016-6489
* Fix sexp-conv crashes on invalid input
* Fix out-of-bounds read in des_weak_p
* Fix a couple of formally undefined shift operations
