CVE-2024-56406 (2025-04-13)

A heap buffer overflow vulnerability was discovered in Perl. Release branches 5.34, 5.36, 5.38 and 5.40 are affected, including development versions from 5.33.1 through 5.41.10. When there are non-ASCII bytes in the left-hand-side of the `tr` operator, `S_do_trans_invmap` can overflow the destination pointer `d`.    $ perl -e '$_ = "\x{FF}" x 1000000; tr/\xFF/\x{100}/;'    Segmentation fault (core dumped) It is believed that this vulnerability can enable Denial of Service and possibly Code Execution attacks on platforms that lack sufficient defenses.

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::Manual::Anatomy::Utilities - Overview of utilities for Test2.

DESCRIPTION

This is a brief overview of the utilities provided by Test2.

Test2::Util

Test2::Util provides functions to help you find out about the current system, or to run generic tasks that tend to be Test2 specific.

This utility provides things like an internal try {...} implementation, and constants for things like threading and forking support.

Test2::Util::ExternalMeta

Test2::Util::ExternalMeta allows you to quickly and easily attach meta-data to an object class.

Test2::Util::Facets2Legacy

Test2::Util::Facets2Legacy is a set of functions you can import into a more recent event class to provide the classic event API.

Test2::Util::HashBase

Test2::Util::HashBase is a local copy of Object::HashBase. All object classes provided by Test2 use this to generate methods and accessors.
