CVE の説明

ExtUtils::Typemaps::STL::List versions before 1.07 for Perl allocate a 32 GiB array on an empty list

ExtUtils::Typemaps::STL::List versions before 1.07 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. Note that a similar issue was fixed in ExtUtils::Typemaps::STL::Vector version 1.05.

CVE の解決策

Upgrade to ExtUtils::Typemaps::Default version 1.07 or later. Rebuild any modules that use ExtUtils::Typemaps::Default as part of their build process.
