Summary

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.
