Description Huzaifa S. Sidhpurwala 2014-07-31 07:59:16 UTC
The version of gmp in rhel-6, lacks the secure exponentiation function mpz_powm_sec ().

As per: https://gmplib.org/manual/Integer-Exponentiation.html the existing mpz_pown() is susceptible to timing attacks and should not be used.

This should be fixed as a result of https://bugzilla.redhat.com/show_bug.cgi?id=1110689 - gmp will be rebased to 6.0.0.
I am not a security expert, could you please take a look if the new build satisfies your needs?

Comment 5 Frantisek Kluknavsky 2014-10-30 15:45:00 UTC
Sorry for the misleading noise, rebase will affect RHEL7.
