CVE-1999-1386 (1999-12-31)

Perl 5.004_04 and earlier follows symbolic links when running with the -e option, which allows local users to overwrite arbitrary files via a symlink attack on the /tmp/perl-eaXXXXX file.

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.

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-1999-0462 (1999-03-17)

suidperl in Linux Perl does not check the nosuid mount option on file systems, allowing local users to gain root access by placing a setuid script in a mountable file system, e.g. a CD-ROM or floppy disk.

CVE-2000-0703 (2000-10-20)

suidperl (aka sperl) does not properly cleanse the escape sequence "~!" before calling /bin/mail to send an error report, which allows local users to gain privileges by setting the "interactive" environmental variable and calling suidperl with a filename that contains the escape sequence.

CVE-2016-1238 (2016-08-02)

(1) cpan/Archive-Tar/bin/ptar, (2) cpan/Archive-Tar/bin/ptardiff, (3) cpan/Archive-Tar/bin/ptargrep, (4) cpan/CPAN/scripts/cpan, (5) cpan/Digest-SHA/shasum, (6) cpan/Encode/bin/enc2xs, (7) cpan/Encode/bin/encguess, (8) cpan/Encode/bin/piconv, (9) cpan/Encode/bin/ucmlint, (10) cpan/Encode/bin/unidump, (11) cpan/ExtUtils-MakeMaker/bin/instmodsh, (12) cpan/IO-Compress/bin/zipdetails, (13) cpan/JSON-PP/bin/json_pp, (14) cpan/Test-Harness/bin/prove, (15) dist/ExtUtils-ParseXS/lib/ExtUtils/xsubpp, (16) dist/Module-CoreList/corelist, (17) ext/Pod-Html/bin/pod2html, (18) utils/c2ph.PL, (19) utils/h2ph.PL, (20) utils/h2xs.PL, (21) utils/libnetcfg.PL, (22) utils/perlbug.PL, (23) utils/perldoc.PL, (24) utils/perlivp.PL, and (25) utils/splain.PL in Perl 5.x before 5.22.3-RC2 and 5.24 before 5.24.1-RC2 do not properly remove . (period) characters from the end of the includes directory array, which might allow local users to gain privileges via a Trojan horse module under the current working directory.

CVE-2015-8608 (2017-02-07)

The VDir::MapPathA and VDir::MapPathW functions in Perl 5.22 allow remote attackers to cause a denial of service (out-of-bounds read) and possibly execute arbitrary code via a crafted (1) drive letter or (2) pInName argument.

NAME

AutoSplit - split a package for autoloading

SYNOPSIS

perl -e 'use AutoSplit; autosplit_lib_modules(@ARGV)' ...

use AutoSplit; autosplit($file, $dir, $keep, $check, $modtime);

for perl versions 5.002 and later:

perl -MAutoSplit -e 'autosplit($ARGV[0], $ARGV[1], $k, $chk, $modtime)' ...

DESCRIPTION

This function will split up your program into files that the AutoLoader module can handle. It is used by both the standard perl libraries and by the MakeMaker utility, to automatically configure libraries for autoloading.

The autosplit interface splits the specified file into a hierarchy rooted at the directory $dir. It creates directories as needed to reflect class hierarchy, and creates the file autosplit.ix. This file acts as both forward declaration of all package routines, and as timestamp for the last update of the hierarchy.

The remaining three arguments to autosplit govern other options to the autosplitter. If the third argument, $keep, is false, then any pre-existing *.al files in the autoload directory are removed if they are no longer part of the module (obsoleted functions). The fourth argument, $check, instructs autosplit to check the module currently being split to ensure that it does include a use specification for the AutoLoader module, and skips the module if AutoLoader is not detected. Lastly, the $modtime argument specifies that autosplit is to check the modification time of the module against that of the autosplit.ix file, and only split the module if it is newer.

Typical use of AutoSplit in the perl MakeMaker utility is via the command-line with:

perl -e 'use AutoSplit; autosplit($ARGV[0], $ARGV[1], 0, 1, 1)'

Defined as a Make macro, it is invoked with file and directory arguments; autosplit will split the specified file into the specified directory and delete obsolete .al files, after checking first that the module does use the AutoLoader, and ensuring that the module is not already currently split in its current form (the modtime test).

The autosplit_lib_modules form is used in the building of perl. It takes as input a list of files (modules) that are assumed to reside in a directory lib relative to the current directory. Each file is sent to the autosplitter one at a time, to be split into the directory lib/auto.

In both usages of the autosplitter, only subroutines defined following the perl special marker __END__ are split out into separate files. Some routines may be placed prior to this marker to force their immediate loading and parsing.

CAVEATS

Currently, AutoSplit cannot handle multiple package specifications within one file.

DIAGNOSTICS

AutoSplit will inform the user if it is necessary to create the top-level directory specified in the invocation. It is preferred that the script or installation process that invokes AutoSplit have created the full directory path ahead of time. This warning may indicate that the module is being split into an incorrect path.

AutoSplit will warn the user of all subroutines whose name causes potential file naming conflicts on machines with drastically limited (8 characters or less) file name length. Since the subroutine name is used as the file name, these warnings can aid in portability to such systems.

Warnings are issued and the file skipped if AutoSplit cannot locate either the __END__ marker or a "package Name;"-style specification.

AutoSplit will also emit general diagnostics for inability to create directories or files.
