Perl: Security Vulnerabilities
Race condition in the rmtree function in File::Path 1.08 and 2.07 (lib/File/Path.pm) in Perl 5.8.8 and 5.10.0 allows local users to create arbitrary setuid binaries via a symlink attack, a different vulnerability than CVE-2005-0448, CVE-2004-0452, and CVE-2008-2827. NOTE: this is a regression error related to CVE-2005-0448. It is different from CVE-2008-5303 due to affected versions.

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.

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.

Perl-Compatible Regular Expression (PCRE) library before 6.7 allows context-dependent attackers to cause a denial of service (error or crash) via a regular expression that involves a "malformed POSIX character class", as demonstrated via an invalid character after a [[ sequence.

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.

The escape_dangerous_chars function in CGI::Lite 2.0 and earlier does not correctly remove special characters including (1) "\" (backslash), (2) "?", (3) "~" (tilde), (4) "^" (carat), (5) newline, or (6) carriage return, which could allow remote attackers to read or write arbitrary files, or execute arbitrary commands, in shell scripts that rely on CGI::Lite to filter such dangerous inputs.

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.
