RHEL 5 : gnupg (RHSA-2014:0016)

low Nessus Plugin ID 71878

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

An updated gnupg package that fixes one security issue is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The GNU Privacy Guard (GnuPG or GPG) is a tool for encrypting data and creating digital signatures, compliant with the proposed OpenPGP Internet standard and the S/MIME standard.

It was found that GnuPG was vulnerable to side-channel attacks via acoustic cryptanalysis. An attacker in close range to a target system that is decrypting ciphertexts could possibly use this flaw to recover the RSA secret key from that system. (CVE-2013-4576)

Red Hat would like to thank Werner Koch of GnuPG upstream for reporting this issue. Upstream acknowledges Genkin, Shamir, and Tromer as the original reporters.

All gnupg users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.

Solution

Update the affected gnupg and / or gnupg-debuginfo packages.
