Integer overflow in the regular expression engine in Perl 5.8.x allows context-dependent attackers to cause a denial of service (stack consumption and application crash) by matching a crafted regular expression against a long string.Show less

The rmtree function in lib/File/Path.pm in Perl 5.10 does not properly check permissions before performing a chmod, which allows local users to modify the permissions of arbitrary files via a symlink attack, a different vulnerability than CVE-2005-0448 and CVE-2004-0452.Show less

Double free vulnerability in Perl 5.8.8 allows context-dependent attackers to cause a denial of service (memory corruption and crash) via a crafted regular expression containing UTF8 characters. NOTE: this issue might only be present on certain operating systems.Show less

Integer overflow in the format string functionality (Perl_sv_vcatpvfn) in Perl 5.9.2 and 5.8.6 Perl allows attackers to overwrite arbitrary memory and possibly execute arbitrary code via format string specifiers with large values, which causes an integer wrap and leads to a buffer overflow, as demonstrated using format string vulnerabilities in Perl applications.Show less
