CVE-2025-40909 (2025-05-30)

Perl threads have a working directory race condition where file operations may target unintended paths. If a directory handle is open at thread creation, the process-wide current working directory is temporarily changed in order to clone that handle for the new thread, which is visible from any third (or more) thread already running. This may lead to unintended operations such as loading code or accessing files from unexpected locations, which a local attacker may be able to exploit. The bug was introduced in commit 11a11ecf4bea72b17d250cfb43c897be1341861e and released in Perl version 5.13.6

NAME

List::Util::XS - Indicate if List::Util was compiled with a C compiler

SYNOPSIS

use List::Util::XS 1.20;

DESCRIPTION

List::Util::XS can be used as a dependency to ensure List::Util was installed using a C compiler and that the XS version is installed.

During installation $List::Util::XS::VERSION will be set to undef if the XS was not compiled.

Starting with release 1.23_03, Scalar-List-Util is always using the XS implementation, but for backwards compatibility, we still ship the List::Util::XS module which just loads List::Util.
