Description

The BN_sqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not properly calculate the square of a BIGNUM value, which might make it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors, related to crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c.

Affected products

OpenSSL: through 0.9.8zc; 1.0.0a, 1.0.0b, 1.0.0c, 1.0.0d, 1.0.0e, 1.0.0f (+19)
