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-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-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-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-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.

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.

NAME

ptargrep - Apply pattern matching to the contents of files in a tar archive

SYNOPSIS

ptargrep [options] <pattern> <tar file> ...

Options:

 --basename|-b     ignore directory paths from archive
 --ignore-case|-i  do case-insensitive pattern matching
 --list-only|-l    list matching filenames rather than extracting matches
 --verbose|-v      write debugging message to STDERR
 --help|-?         detailed help message

DESCRIPTION

This utility allows you to apply pattern matching to the contents of files contained in a tar archive. You might use this to identify all files in an archive which contain lines matching the specified pattern and either print out the pathnames or extract the files.

The pattern will be used as a Perl regular expression (as opposed to a simple grep regex).

Multiple tar archive filenames can be specified - they will each be processed in turn.

OPTIONS

--basename (alias -b)

When matching files are extracted, ignore the directory path from the archive and write to the current directory using the basename of the file from the archive. Beware: if two matching files in the archive have the same basename, the second file extracted will overwrite the first.

--ignore-case (alias -i)

Make pattern matching case-insensitive.

--list-only (alias -l)

Print the pathname of each matching file from the archive to STDOUT. Without this option, the default behaviour is to extract each matching file.

--verbose (alias -v)

Log debugging info to STDERR.

--help (alias -?)

Display this documentation.
