Summary

ExtUtils::Typemaps::STL::Vector for Perl versions before 1.05 are affected. The OUTPUT typemaps call av_extend with len-1, which underflows on an empty list (CWE-191). This makes av_extend allocate an array with 2^32 slots, a 32 GiB array, which exhausts memory.

Description from the CNA

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.
