(RHSA-2003:257) perl security update

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

Two security issues have been found in Perl that affect the Perl packages
shipped with Red Hat Enterprise Linux:

When safe.pm versions 2.0.7 and earlier are used with Perl 5.8.0 and
earlier, it is possible for an attacker to break out of safe compartments
within Safe::reval and Safe::rdo by using a redefined @_ variable. This is
due to the fact that the redefined @_ variable is not reset between
successive calls. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2002-1323 to this issue.

A cross-site scripting vulnerability was discovered in the start_form()
function of CGI.pm. The vulnerability allows a remote attacker to insert a
Web script via a URL fed into the form’s action parameter. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0615 to this issue.

Users of Perl are advised to upgrade to these erratum packages, which
contain Perl 5.6.1 with backported security patches correcting these issues.
