RHEL 6 : libtar (RHSA-2013:1418)

medium Nessus Plugin ID 70387

Language:

Synopsis

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

Description

An updated libtar package that fixes one security issue is now available for Red Hat Enterprise Linux 6.

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 libtar package contains a C library for manipulating tar archives.
The library supports both the strict POSIX tar format and many of the commonly used GNU extensions.

Two heap-based buffer overflow flaws were found in the way libtar handled certain archives. If a user were tricked into expanding a specially crafted archive, it could cause the libtar executable or an application using libtar to crash or, potentially, execute arbitrary code. (CVE-2013-4397)

Note: This issue only affected 32-bit builds of libtar.

Red Hat would like to thank Timo Warns for reporting this issue.

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

Solution

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