Integer Overflow in ExtUtils::Typemaps::STL::Vector for Perl

Publication date: 2026-10-10

Last updated on: 2026-10-10

Assigner: CPANSec

Description
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.

Executive Summary

This vulnerability affects the ExtUtils::Typemaps::STL::Vector Perl module versions before 1.05. When processing an empty list, the module incorrectly calls av_extend with a negative index, causing it to allocate a 32 GiB array. This leads to memory exhaustion and potential system instability.

Detection Guidance

This vulnerability is specific to the ExtUtils::Typemaps::STL::Vector Perl module. To detect it, check if the installed version of the module is before 1.05 using Perl commands like 'cpan ExtUtils::Typemaps::STL::Vector' or inspect the module version in your Perl environment.

Impact Analysis

The vulnerability can cause denial of service by exhausting system memory. Applications using the affected Perl module may crash or become unresponsive when processing empty lists, disrupting normal operations.

Mitigation Strategies

Update the ExtUtils::Typemaps::STL::Vector module to version 1.05 or later. This can be done using Perl's CPAN client with the command 'cpan ExtUtils::Typemaps::STL::Vector' or by applying the patch from the provided GitHub commit.
