Medium Nessus Plugin ID 20367


The remote Red Hat host is missing one or more security updates.


Updated Perl packages that fix security issues and bugs are now available for Red Hat Enterprise Linux 3.

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

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

An integer overflow bug was found in Perl's format string processor.
It is possible for an attacker to cause perl to crash or execute arbitrary code if the attacker is able to process a malicious format string. This issue is only exploitable through a script wich passes arbitrary untrusted strings to the format string processor. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-3962 to this issue.

Paul Szabo discovered a bug in the way Perl's File::Path::rmtree module removed directory trees. If a local user has write permissions to a subdirectory within the tree being removed by File::Path::rmtree, it is possible for them to create setuid binary files. (CVE-2005-0448)

Solar Designer discovered several temporary file bugs in various Perl modules. A local attacker could overwrite or create files as the user running a Perl script that uses a vulnerable module. (CVE-2004-0976)

Users of Perl are advised to upgrade to these updated packages, which contain backported patches to correct these issues as well as fixes for several bugs.


Update the affected packages.
