Debian Linux Security Advisory 3296-1 - Evgeny Sidorov discovered that libcrypto++, a general purpose C++ cryptographic library, 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.

Package : libcrypto++
CVE ID : CVE-2015-2141
Evgeny Sidorov discovered that libcrypto++, a general purpose C++
cryptographic library, 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.
