Hi New versions of 'nettle/libnettle4/libhogweed2/libnettle-devel' have been uploaded to a server near you.
o Build for cygwin 2.4.1-1 with gcc-5.3.0-3 o Update to 2.7.1 o Fix for CVEs, see https://cygwin.com/ml/cygwin-apps/2016-03/msg00000.html nettle NEWS: ============ * Fixed a bug in the new ECC code. The ecc_j_to_a function called GMP:s mpn_mul_n (via ecc_modp_mul) with overlapping input and output arguments, which is not supported. * The assembly files for SHA1, SHA256 and AES depend on ARMv6 instructions, breaking nettle-2.7 for pre-v6 ARM processors. The configure script now enables those assembly files only when building for ARMv6 or later. * Use a more portable C expression for rotations. The previous version used the following "standard" expression for 32-bit rotation: (x << n) | (x >> (32 - n)) But this gives undefined behavior (according to the C specification) for n = 0. The rotate expression is replaced by the more portable: (x << n) | (x >> ((-n)&31)) This change affects only CAST128, which uses non-constant rotation counts. Unfortunately, the new expression is poorly optimized by released versions of gcc, making CAST128 a bit slower. This is being fixed by the gcc hackers, see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57157.
