The Crypt::DSA (aka Crypt-DSA) module 1.17 and earlier for Perl, when /dev/random is absent, uses the Data::Random module, which makes it easier for remote attackers to spoof a signature, or determine the signing key of a signed message, via a brute-force attack.

The Data::FormValidator module 4.66 and earlier for Perl, when untaint_all_constraints is enabled, does not properly preserve the taint attribute of data, which might allow remote attackers to bypass the taint protection mechanism via form input.

The Safe (aka Safe.pm) module before 2.25 for Perl allows context-dependent attackers to bypass intended (1) Safe::reval and (2) Safe::rdo access restrictions, and inject and execute arbitrary code, via vectors involving implicitly called methods and implicitly blessed objects, as demonstrated by the (a) DESTROY and (b) AUTOLOAD methods, related to "automagic methods."

Off-by-one error in the bzinflate function in Bzip2.xs in the Compress-Raw-Bzip2 module before 2.018 for Perl allows context-dependent attackers to cause a denial of service (application hang or crash) via a crafted bzip2 compressed stream that triggers a buffer overflow, a related issue to CVE-2009-1391.
