PerlRun.pm in Apache mod_perl before 1.30, and RegistryCooker.pm in mod_perl 2.x, does not properly escape PATH_INFO before use in a regular expression, which allows remote attackers to cause a denial of service (resource...

Imager (libimager-perl) before 0.50 allows user-assisted attackers to cause a denial of service (segmentation fault) by writing a 2- or 4-channel JPEG image (or a 2-channel TGA image) to a scalar, which triggers a NULL pointer dereference.

CGI::Session 4.03-1 does not set proper permissions on temporary files created in (1) Driver::File and (2) Driver::db_file, which allows local users to obtain privileged information, such as session keys, by viewing the files.

CGI::Session 4.03-1 allows local users to overwrite arbitrary files via a symlink attack on temporary files used by (1) Driver::File, (2) Driver::db_file, and possibly (3) Driver::sqlite.

Crypt::CBC Perl module 2.16 and earlier, when running in RandomIV mode, uses an initialization vector (IV) of 8 bytes, which results in weaker encryption when used with a cipher that requires a larger block size than 8 bytes, such...

Mail::Audit module in libmail-audit-perl 2.1-5, when logging is enabled without a default log file specified, uses predictable log filenames, which allows local users to overwrite arbitrary files via a symlink attack on...
