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.
