What is CVE-2014-3570?
CVE-2014-3570 is a medium-severity vulnerability in Openssl Openssl, published on 9 Jan 2015. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
