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.

This update is available via Red Hat Network. Details on how to use
