NewCVE-2026-107794 (opens in a new tab)How to fix?
There is no fixed version for Echo:latest libextutils-typemaps-default-perl.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libextutils-typemaps-default-perl package and not the libextutils-typemaps-default-perl package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
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.
