n/openssl-1.0.2m-x86_64-1.txz
This update fixes a security issue:
There is a carry propagating bug in the x64 Montgomery squaring procedure.
No EC algorithms are affected. Analysis suggests that attacks against RSA
and DSA as a result of this defect would be very difficult to perform and
are not believed likely. Attacks against DH are considered just feasible
(although very difficult) because most of the work necessary to deduce
information about a private key may be performed offline. The amount of
resources required for such an attack would be very significant and likely
only accessible to a limited number of attackers. An attacker would
additionally need online access to an unpatched system using the target
private key in a scenario with persistent DH parameters and a private
key that is shared between multiple clients.
This only affects processors that support the BMI1, BMI2 and ADX extensions
like Intel Broadwell (5th generation) and later or AMD Ryzen.
