RHSA-2005-103: perl

Vulnerability Assessment Summary
Check for the version of the perl packages

Detailed Explanation for this Vulnerability Assessment

Updated Perl packages that fix several security issues are now available
for Red Hat Enterprise Linux 4.

This update has been rated as having important 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.

Kevin Finisterre discovered a stack based buffer overflow flaw in sperl,
the Perl setuid wrapper. A local user could create a sperl executable
script with a carefully created path name, overflowing the buffer and
leading to root privilege escalation. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2005-0156 to
this issue.

Kevin Finisterre discovered a flaw in sperl which can cause debugging
information to be logged to arbitrary files. By setting an environment
variable, a local user could cause sperl to create, as root, files with
arbitrary filenames, or append the debugging information to existing files.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2005-0155 to this issue.

An unsafe file permission bug was discovered in the rmtree() function in
the File::Path module. The rmtree() function removes files and directories
in an insecure manner, which could permit a local user to read or delete
arbitrary files. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0452 to this issue.

Users of Perl are advised to upgrade to this updated package, which
contains backported patches to correct these issues.
