CVE-2026-4176 (2026-03-29)

Perl versions from 5.9.4 before 5.40.4-RC1, from 5.41.0 before 5.42.2-RC1, from 5.43.0 before 5.43.9 contain a vulnerable version of Compress::Raw::Zlib. Compress::Raw::Zlib is included in the Perl package as a dual-life core module, and is vulnerable to CVE-2026-3381 due to a vendored version of zlib which has several vulnerabilities, including CVE-2026-27171. The bundled Compress::Raw::Zlib was updated to version 2.221 in Perl blead commit c75ae9cc164205e1b6d6dbd57bd2c65c8593fe94.

CVE-2026-8376 (2026-05-25)

Perl versions through 5.43.10 have a heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds. Perl_study_chunk in regcomp_study.c checked the size of the joined substring buffer in characters rather than bytes. For a quantified fixed substring with a large minimum count, the byte length mincount * l could overflow SSize_t, producing an undersized SvGROW allocation; the subsequent copy writes past the end of the buffer. A caller that compiles an attacker-controlled regular expression on a 32-bit perl build triggers a heap buffer overflow at compile time.

NAME

Test::RRA::ModuleVersion - Check Perl module versions for consistency

SYNOPSIS

use Test::RRA::ModuleVersion
  qw(test_module_versions update_module_versions);

# Ensure all modules under perl/lib have a version of v3.1.2.
test_module_versions('perl/lib', 'v3.1.2');

# Update the version of those modules to v3.1.2.
update_module_versions('perl/lib', 'v3.1.2');

DESCRIPTION

This module provides functions to test and update the versions of Perl modules. It helps with enforcing consistency of versioning across all modules in a Perl distribution or embedded in a larger project containing non-Perl code. The calling script provides the version with which to be consistent and the root directory under which modules are found.

FUNCTIONS

None of these functions are imported by default. The ones used by a script should be explicitly imported.

test_module_versions(ROOT, VERSION)

Tests the version of all Perl modules under ROOT to ensure they match VERSION, reporting the results with Test::More. VERSION should include any leading v.

If the test configuration loaded by Test::RRA::Config contains a @MODULE_VERSION_EXCLUDE variable, the module files listed there will be ignored for this test.

This function sets up a plan based on the number of modules, so should be the only testing function called in a test script.

update_module_versions(ROOT, VERSION)

Update the version of all Perl modules found under ROOT to VERSION, except for any listed in a @MODULE_VERSION_EXCLUDE variable set in the test configuration loaded by Test::RRA::Config. VERSION should include any leading v.
