MDKSA-2005:031: perl Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the perl package

Detailed Explanation for this Vulnerability Test

The remote host is missing the patch for the advisory MDKSA-2005:031 (perl).

Jeroen van Wolffelaar discovered that the rmtree() function in the perl
File::Path module would remove directories in an insecure manner which could
lead to the removal of arbitrary files and directories via a symlink attack

Trustix developers discovered several insecure uses of temporary files in many
modules which could allow a local attacker to overwrite files via symlink
attacks (CVE-2004-0976).

'KF' discovered two vulnerabilities involving setuid-enabled perl scripts. By
setting the PERLIO_DEBUG environment variable and calling an arbitrary
setuid-root perl script, a possible hacker could overwrite arbitrary files with perl
debug messages (CVE-2005-0155). As well, calling a setuid-root perl script with
a very long path would cause a buffer overflow if PERLIO_DEBUG was set, which
could be exploited to execute arbitrary files with root rights

The provided packages have been patched to resolve these problems.
