Summary
Red Hat Security Advisory: perl security update

Notes

Topic
Updated Perl packages that fix a security issue in Safe.pm and a cross-site scripting (XSS) vulnerability in CGI.pm are now available.
Details
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.
