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::Tooling - Manual page for tool authors.

DESCRIPTION

This section covers writing new tools, plugins, and other Test2 components.

TOOL TUTORIALS

FIRST TOOL

Test2::Manual::Tooling::FirstTool - Introduction to writing tools by cloning ok().

MOVING FROM Test::Builder

Test2::Manual::Tooling::TestBuilder - This section maps Test::Builder methods to Test2 concepts.

NESTING TOOLS

Test2::Manual::Tooling::Nesting - How to call other tools from your tool.

TOOLS WITH SUBTESTS

Test2::Manual::Tooling::Subtest - How write tools that make use of subtests.

TESTING YOUR TEST TOOLS

Test2::Manual::Tooling::Testing - How to write tests for your test tools.

PLUGIN TUTORIALS

TAKING ACTION WHEN A NEW TOOL STARTS

Test2::Manual::Tooling::Plugin::ToolStarts - How to add behaviors that occur when a tool starts work.

TAKING ACTION AFTER A TOOL IS DONE

Test2::Manual::Tooling::Plugin::ToolCompletes - How to add behaviors that occur when a tool completes work.

TAKING ACTION AT THE END OF TESTING

Test2::Manual::Tooling::Plugin::TestingDone - How to add behaviors that occur when testing is complete (IE done_testing, or end of test).

TAKING ACTION JUST BEFORE EXIT

Test2::Manual::Tooling::Plugin::TestExit - How to safely add pre-exit behaviors.

WRITING A SIMPLE JSONL FORMATTER

Test2::Manual::Tooling::Formatter - How to write a custom formatter, in our case a JSONL formatter.

WHERE TO FIND HOOKS AND APIS

global API

Test2::API is the global API. This is primarily used by plugins that provide global behavior.

In hubs

Test2::Hub is the base class for all hubs. This is where hooks for manipulating events, or running things at the end of testing live.

SEE ALSO
