openSUSE Recommended Update: Botan: Fix unsafe Miller-Rabin test. ______________________________________________________________________________ Announcement ID: openSUSE-RU-2014:0680-1 Rating: moderate References: Affected Products: openSUSE 13.1 openSUSE 12.3 ______________________________________________________________________________ An update that has 0 recommended fixes can now be installed. Description: This update fixes the following issue with Botan: - Fix a bug in primality testing introduced in 1.8.3 which caused only a single random base, rather than a sequence of random bases, to be used in the Miller-Rabin test. This increased the probability that a non-prime would be accepted, for instance a 1024 bit number would be incorrectly classed as prime with probability around 2^-40.
