CVE-2015-2141

The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.2 does not properly blind private key operations for the Rabin-Williams digital signature algorithm, which allows remote attackers to obtain private keys via a timing attack.

Evgeny Sidorov discovered that libcryptopp did not properly implement blinding to mask private key operations for the Rabin-Williams digital signature algorithm. This could allow remote attackers to mount a timing attack and retrieve the user's private key (CVE-2015-2141).

These are all security issues fixed in the libcryptopp-devel-5.6.4-1.3 package on the GA media of openSUSE Tumbleweed.
