CVE-2013-10076

Summary

A Perl module flaw allows attackers to trigger a memory exhaustion attack by exploiting an integer underflow in array allocation. When processing empty lists, the module allocates a massive 32 GiB array instead of a small one, leading to system resource exhaustion.

Exploitability

Exploitation is moderately difficult as it requires crafting specific input data that triggers the STL::Vector typemap processing with empty lists, but the attack can be automated once the trigger conditions are met.

Blast radius

The impact could be significant in environments where Perl applications process untrusted input through ExtUtils::Typemaps::STL::Vector, potentially leading to service disruption or denial of service across multiple processes.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to ExtUtils::Typemaps::STL::Vector version 1.05 or later to fix the integer underflow issue.
