Perl vulnerabilitiesRanked by how likely they are to be used.
Perl is made by Larry Wall. We track 12 published vulnerabilities in it, across 18 versions. None of them is on the list of flaws known to be exploited today. If you run Perl, keep it on a version the vendor still supports.
We keep watching the known-exploited list.

Which Perl flaws are most likely to be used?
Ranked by the latest exploit-likelihood forecast: the chance each flaw is used in an attack in the next 30 days. A high severity score on its own doesn't tell you that. Flaws shared by many other makers' products are left out.
- 8.0%CVE-2004-2286High
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.
- 6.8%CVE-2004-0377Critical
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...
- 4.8%CVE-2007-5116High
Buffer overflow in the polymorphic opcode support in the Regular Expression Engine (regcomp.c) in Perl 5.8 allows context-dependent attackers to execute arbitrary code by switching from byte to Unicode (UTF)...
- 1.4%CVE-2003-0900Medium
Perl 5.8.1 on Fedora Core does not properly initialize the random number generator when forking, which makes it easier for attackers to predict random numbers.
- 1.3%
Buffer overflow in the PerlIO implementation in Perl 5.8.0, when installed with setuid support (sperl), allows local users to execute arbitrary code by setting the PERLIO_DEBUG variable and executing a Perl script...
- 1.2%CVE-2005-0155Medium
The PerlIO implementation in Perl 5.8.0, when installed with setuid support (sperl), allows local users to create arbitrary files via the PERLIO_DEBUG variable.
- 1.2%CVE-1999-0034High
Buffer overflow in suidperl (sperl), Perl 4.x and 5.x.
- 1.1%CVE-2000-0703High
suidperl (aka sperl) does not properly cleanse the escape sequence "~!" before calling /bin/mail to send an error report, which allows local users to gain privileges by setting the "interactive" environmental...
- 0.4%
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.
- 0.4%
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...
