Mandrake Linux Security Advisory : perl (MDKSA-2005:031)
Medium Nessus Plugin ID 16360
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionJeroen 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 (CVE-2004-0452).
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, an attacker 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 privileges (CVE-2005-0156).
The provided packages have been patched to resolve these problems.
SolutionUpdate the affected packages.
