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-2018-18314 (2018-12-07)

Perl before 5.26.3 has a buffer overflow via a crafted regular expression that triggers invalid write operations.

CVE-2018-18313 (2018-12-07)

Perl before 5.26.3 has a buffer over-read via a crafted regular expression that triggers disclosure of sensitive information from process memory.

CVE-2018-18312 (2018-12-05)

Perl before 5.26.3 and 5.28.0 before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.

CVE-2018-18311 (2018-12-07)

Perl before 5.26.3 and 5.28.x before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.

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

Porting/sync-with-cpan - Synchronize with CPAN distributions

SYNOPSIS

perl Porting/sync-with-cpan <module>

where <module> is the name it appears in the %Modules hash of Porting/Maintainers.pl

DESCRIPTION

Script to help out with syncing cpan distros.

Does the following:

  • Fetches the package list from CPAN. Finds the current version of the given package. [1]

  • Downloads the relevant tarball; unpacks the tarball. [1]

  • Clean out the old directory (git clean -dfx)

  • Moves the old directory out of the way, moves the new directory in place.

  • Restores any .gitignore file.

  • Removes files from @IGNORE and EXCLUDED

  • git add any new files.

  • git rm any files that are gone.

  • Remove the +x bit on files in t/

  • Remove the +x bit on files that don't have it enabled in the current dir

  • Restore files mentioned in CUSTOMIZED

  • Adds new files to MANIFEST

  • Runs a make (assumes a configure has been run)

  • Cleans up

  • Runs tests for the package

  • Runs the porting tests

[1] If the --tarball option is given, then CPAN is not consulted. --tarball should be the path to the tarball; the version is extracted from the filename -- but can be overwritten by the --version option.

TODO

  • Delete files from MANIFEST

  • Update Porting/Maintainers.pl

  • Optional, run a full test suite

  • Handle complicated FILES

This is an initial version; no attempt has been made yet to make this portable. It shells out instead of trying to find a Perl solution. In particular, it assumes git, perl, and make to be available.
