Title:	Ubuntu 4.10 USN-72-1 (perl)
Summary:	NOSUMMARY
Description:	Description: The remote host is missing an update to perl announced via advisory USN-72-1. Two exploitable vulnerabilities involving setuid-enabled perl scripts have been discovered. The package 'perl-suid' provides a wrapper around perl which allows to use setuid-root perl scripts, i.e. user-callable Perl scripts which have full root privileges. Previous versions allowed users to overwrite arbitrary files by setting the PERLIO_DEBUG environment variable and calling an arbitrary setuid-root perl script. The file that PERLIO_DEBUG points to was then overwritten by Perl debug messages. This did not allow precise control over the file content, but could destroy important data. PERLIO_DEBUG is now ignored for setuid scripts. (CVE-2005-0155) In addition, calling a setuid-root perl script with a very long path caused a buffer overflow if PERLIO_DEBUG was set. This buffer overflow could be exploited to execute arbitrary files with full root privileges. (CVE-2005-0156) The following packages are affected: perl Solution: The problem can be corrected by upgrading the affected package to version 5.8.4-2ubuntu0.3. In general, a standard system upgrade is sufficient to effect the necessary changes. http://lists.ubuntu.com/archives/ubuntu-security-announce/2005-February/000074.html Risk factor : Medium CVSS Score: 4.6
