3. Description:

Perl is a high-level programming language commonly used for system
administration utilities and Web programming.

A flaw was found in Perl's regular expression engine. A specially crafted
regular expression with Unicode characters could trigger a buffer overflow,
causing Perl to crash, or possibly execute arbitrary code with the
privileges of the user running Perl. (CVE-2008-1927)

Users of perl are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

the Red Hat Network to apply this update are available at
