Added to an existing GLSA Request. This issue was resolved and addressed in GLSA 201612-16 at https://security.gentoo.org/glsa/201612-16 by GLSA coordinator Aaron Bauman (b-man). |
From ${URL} : An out-of-bounds write vulnerability was found to be caused by not checking errors in BN_bn2dec(). If an oversize BIGNUM is presented to BN_bn2dec() it can cause BN_div_word() to fail and not reduce the value of 't' resulting in OOB writes to the bn_data buffer and eventually crashing. Upstream patch: https://git.openssl.org/?p=openssl.git;a=commit;h=07bed46f332fce8c1d157689a2cdf915a982ae34 @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
