Debian DLA-262-1 : libcrypto++ security update

medium Nessus Plugin ID 84473

Synopsis

The remote Debian host is missing a security 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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
