Buffer overflow in suidperl (sperl), Perl 4.x and 5.x.

Perl 5.004_04 and earlier follows symbolic links when running with the -e option, which allows local users to overwrite arbitrary files via a symlink attack on the /tmp/perl-eaXXXXX file.

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 variable and calling suidperl with a filename that contains the escape sequence.

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.

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.

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.

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.

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.

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 whose full pathname contains a long directory tree.

Race condition in the rmtree function in File::Path.pm in Perl before 5.8.4 allows local users to create arbitrary setuid binaries in the tree being deleted, a different vulnerability than CVE-2004-0452.

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.
