Description Agostino Sarubbo gentoo-dev 2016-08-17 11:45:49 UTC
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:;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.
