"An updated file package that fixes a security flaw is now available
for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The file command is used to identify a particular file according to
the type of data contained by the file.

An integer underflow flaw was found in the file utility. An attacker
could create a carefully crafted file which, if examined by a victim
using the file utility, could lead to arbitrary code execution.
(CVE-2007-1536)

This issue did not affect the version of the file utility distributed
with Red Hat Enterprise Linux 2.1 or 3.

Users should upgrade to this erratum package, which contain a
backported patch to correct this issue."
