RHEL 6 / 7 : lzo (RHSA-2014:0861)

Medium Nessus Plugin ID 76445


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


Updated lzo packages that fix one security issue are now available for Red Hat Enterprise Linux 6 and 7.

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.

LZO is a portable lossless data compression library written in ANSI C.

An integer overflow flaw was found in the way the lzo library decompressed certain archives compressed with the LZO algorithm. An attacker could create a specially crafted LZO-compressed input that, when decompressed by an application using the lzo library, would cause that application to crash or, potentially, execute arbitrary code.

Red Hat would like to thank Don A. Bailey from Lab Mouse Security for reporting this issue.

All lzo users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all services linked to the lzo library must be restarted or the system rebooted.


Update the affected packages.
