RHSA-2005-881: perl Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the perl packages

Detailed Explanation for this Vulnerability Test

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 a possible hacker 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.
