Debian DSA-3296-1 : libcrypto++ - security update

medium Nessus Plugin ID 84436

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the libcrypto++ packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 5.6.1-6+deb7u1.

For the stable distribution (jessie), this problem has been fixed in version 5.6.1-6+deb8u1.
