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

Locale::Script - module for dealing with script code sets

SYNOPSIS

use Locale::Script;

$name = code2script(CODE);
$code = script2code(NAME);

@codes   = all_script_codes();
@names   = all_script_names();

DESCRIPTION

This module provides access to script code sets.

Please refer to the Locale::Codes::Types document for a description of the code sets available.

Most of the routines take an optional additional argument which specifies the code set to use. The code set can be specified using the name of a code set, or the perl constant specified in the above document. If not specified, the default code set will be used.

ROUTINES

All routines in this module call the appropriate method in the Locale::Codes module, using an object of type: script Please refer to the documentation of the Locale::Codes module for details about each function.

The following functions are exported automatically:

code2script(CODE [,CODESET] [,'retired'])

See code2name in Locale::Codes

script2code(NAME [,CODESET] [,'retired'])

See name2code in Locale::Codes

script_code2code(CODE ,CODESET ,CODESET2)

See code2code in Locale::Codes

all_script_codes([CODESET] [,'retired'])

See all_codes in Locale::Codes

all_script_names([CODESET] [,'retired'])

See all_names in Locale::Codes

The following functions are not exported and must be called fully qualified with the package name:

Locale::Script::show_errors(FLAG)

By default, invalid input will produce empty results, but no errors. By passing in a non-zero value of FLAG, errors will be produced.

See show_errors in Locale::Codes but note that the default for the non-OO modules are to NOT produce errors.

Locale::Script::rename_script(CODE ,NEW_NAME [,CODESET])

See rename_code in Locale::Codes

Locale::Script::add_script(CODE ,NAME [,CODESET])

See add_code in Locale::Codes

Locale::Script::delete_script(CODE [,CODESET])

See delete_code in Locale::Codes

Locale::Script::add_script_alias(NAME ,NEW_NAME)

See add_alias in Locale::Codes

Locale::Script::delete_script_alias(NAME)

See delete_alias in Locale::Codes

Locale::Script::rename_script_code(CODE ,NEW_CODE [,CODESET])

See replace_code in Locale::Codes

Locale::Script::add_script_code_alias(CODE ,NEW_CODE [,CODESET])

See add_code_alias in Locale::Codes

Locale::Script::delete_script_code_alias(CODE [,CODESET])

See delete_code_alias in Locale::Codes
