RHSA-2010:0061 - Moderate: gzip security update
Synopsis
Moderate: gzip security update
Type/Severity
Security Advisory Moderate
Topic
An updated gzip package that fixes one security issue is now available for Red Hat Enterprise Linux 3, 4, and 5.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
Description
The gzip package provides the GNU gzip data compression program.
An integer underflow flaw, leading to an array index error, was found in the way gzip expanded archive files compressed with the Lempel-Ziv-Welch (LZW) compression algorithm. If a victim expanded a specially-crafted archive, it could cause gzip to crash or, potentially, execute arbitrary code with the privileges of the user running gzip. This flaw only affects 64-bit systems. (CVE-2010-0001)
Red Hat would like to thank Aki Helin of the Oulu University Secure Programming Group for responsibly reporting this flaw.
Users of gzip should upgrade to this updated package, which contains a backported patch to correct this issue.
Solution
Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
