=========================================================== Ubuntu Security Notice USN-72-1 February 02, 2005 perl vulnerabilities CAN-2005-0155, CAN-2005-0156 ===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
The following packages are affected:
perl
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.
Details follow:
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. (CAN-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. (CAN-2005-0156)
