Vulnerability Assessment Details
Detailed Explanation for this Vulnerability Assessment
These remote packages are missing security patches :
Two exploitable vulnerabilities involving setuid-enabled perl scripts
have been discovered. The package "perl-suid" provides a wrapper
around perl which permits to use setuid-root perl scripts, i.e.
user-callable Perl scripts which have full root rights.
Previous versions permited 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 permit 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
