Unspecified vulnerability in Positive Software Corporation CP+ (cpplus) before 2.5.5 allows attackers to have unknown impact and attack vectors, related to "a possible security flaw caused by a bug in Perl." NOTE: unless CP+ includes its own copy of Perl with CVE-2005-3962, this is a different vulnerability than CVE-2005-3962; however, there is insufficient information to be sure.

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.
