Larry Wall » Perl » 5.6.1 : Security Vulnerabilities, CVEs,

Buffer overflow in the win32_stat function for (1) ActiveState's ActivePerl and (2) Larry Wall's Perl before 5.8.3 allows local or remote attackers to execute arbitrary commands via filenames that end in a backslash character.

Integer overflow in the duplication operator in ActivePerl allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large multiplier, which may trigger a buffer overflow.

Untrusted search path vulnerability in Perl before 5.8.7-r1 on Gentoo Linux allows local users in the portage group to gain privileges via a malicious shared object in the Portage temporary build directory, which is part of the RUNPATH.

Race condition in the rmtree function in the File::Path module in Perl 5.6.1 and 5.8.4 sets read/write permissions for the world, which allows local users to delete arbitrary files and directories, and possibly read files and directories, via a symlink attack.

Multiple scripts in the perl package in Trustix Secure Linux 1.5 through 2.1 and other operating systems allows local users to overwrite files via a symlink attack on temporary files.
