CVE-2013-10076

ExtUtils::Typemaps::STL::Vector versions before 1.05 for Perl allocate a 32 GiB array on an empty list.

Published Oct 10, 2026 · updated Oct 15, 2026

ExtUtils::Typemaps::STL::Vector versions before 1.05 for Perl allocate a 32 GiB array on an empty list. The OUTPUT typemaps call av_extend( av, len-1 ). On an empty list, this undeflows, and av_extend will allocate an array with 2^32 slots, leading to memory exhaustion.
