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

Test2::Util::Ref - Tools for inspecting or manipulating references.

DESCRIPTION

These are used by Test2::Tools to inspect, render, or manipulate references.

EXPORTS

All exports are optional. You must specify subs to import.

$type = rtype($ref)

A normalization between Scalar::Util::reftype() and ref().

Always returns a string.

Returns 'REGEXP' for regex types

Returns '' for non-refs

Otherwise returns what Scalar::Util::reftype() returns.

$addr_str = render_ref($ref)

Always returns a string. For unblessed references this returns something like "SCALAR(0x...)". For blessed references it returns "My::Thing=SCALAR(0x...)". The only difference between this and $add_str = "$thing" is that it ignores any overloading to ensure it is always the ref address.
