Scientific Linux Security Update : libgcrypt on SL5.x, SL6.x i386/x86_64 (20131024)

low Nessus Plugin ID 70605

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

It was found that GnuPG was vulnerable to the Yarom/Falkner flush+reload cache side-channel attack on the RSA secret exponent. An attacker able to execute a process on the logical CPU that shared the L3 cache with the GnuPG process (such as a different local user or a user of a KVM guest running on the same host with the kernel same-page merging functionality enabled) could possibly use this flaw to obtain portions of the RSA secret key. (CVE-2013-4242)

Solution

Update the affected libgcrypt, libgcrypt-debuginfo and / or libgcrypt-devel packages.
