CVE-2020-12723 (2020-06-05)

regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.

CVE-2020-10878 (2020-06-05)

Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection.

CVE-2020-10543 (2020-06-05)

Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow.

CVE-2018-6798 (2018-04-17)

An issue was discovered in Perl 5.22 through 5.26. Matching a crafted locale dependent regular expression can cause a heap-based buffer over-read and potentially information disclosure.

CVE-2023-47100

In Perl before 5.38.2, S_parse_uniprop_string in regcomp.c can write to unallocated space because a property name associated with a \p{...} regular expression construct is mishandled. The earliest affected version is 5.30.0.

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

A heap buffer overflow vulnerability was discovered in Perl. 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

CVE-2023-47039 (2023-10-30)

Perl for Windows relies on the system path environment variable to find the shell (cmd.exe). When running an executable which uses Windows Perl interpreter, Perl attempts to find and execute cmd.exe within the operating system. However, due to path search order issues, Perl initially looks for cmd.exe in the current working directory. An attacker with limited privileges can exploit this behavior by placing cmd.exe in locations with weak permissions, such as C:\ProgramData. By doing so, when an administrator attempts to use this executable from these compromised locations, arbitrary code can be executed.

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 3.12.
test_module_versions('perl/lib', '3.12');

# Update the version of those modules to 3.12.
update_module_versions('perl/lib', 3.12');

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. 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 also 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.
