CVE-2016-6185 (2016-08-02)

The XSLoader::load method in XSLoader in Perl does not properly locate .so files when called in a string eval, which might allow local users to execute arbitrary code via a Trojan horse library under the current working directory.

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-2018-6797 (2018-04-17)

An issue was discovered in Perl 5.18 through 5.26. A crafted regular expression can cause a heap-based buffer overflow, with control over the bytes written.

CVE-2018-6913 (2018-04-17)

Heap-based buffer overflow in the pack function in Perl before 5.26.2 allows context-dependent attackers to execute arbitrary code via a large item count.

CVE-2018-18314 (2018-12-07)

CVE-2017-12883 (2017-09-19)

Buffer overflow in the S_grok_bslash_N function in regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 allows remote attackers to disclose sensitive information or cause a denial of service (application crash) via a crafted regular expression with an invalid '\\N{U+...}' escape.

CVE-2017-12837 (2017-09-19)

Heap-based buffer overflow in the S_regatom function in regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 allows remote attackers to cause a denial of service (out-of-bounds write) via a regular expression with a '\\N{}' escape and the case-insensitive modifier.

CVE-2015-8853 (2016-05-25)

The (1) S_reghop3, (2) S_reghop4, and (3) S_reghopmaybe3 functions in regexec.c in Perl before 5.24.0 allow context-dependent attackers to cause a denial of service (infinite loop) via crafted utf-8 data, as demonstrated by "a\x80."

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-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-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-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.

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.

NAME

Locale::Codes::Country - standard codes for country identification

SYNOPSIS

use Locale::Codes::Country;

$country = code2country('jp' [,CODESET]);        # $country gets 'Japan'
$code    = country2code('Norway' [,CODESET]);    # $code gets 'no'

@codes   = all_country_codes( [CODESET]);
@names   = all_country_names();

# semi-private routines
Locale::Codes::Country::alias_code('uk' => 'gb');
Locale::Codes::Country::rename_country('gb' => 'Great Britain');

DESCRIPTION

This module provides access to several code sets that can be used for identifying countries, such as those defined in ISO 3166-1.

Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 3166-1 two-letter codes will be used.

SUPPORTED CODE SETS

There are several different code sets you can use for identifying countries. A code set may be specified using either a name, or a constant that is automatically exported by this module.

For example, the two are equivalent:

$country = code2country('jp','alpha-2');
$country = code2country('jp',LOCALE_CODE_ALPHA_2);

The codesets currently supported are:

alpha-2, LOCALE_CODE_ALPHA_2

This is the set of two-letter (lowercase) codes from ISO 3166-1, such as 'tv' for Tuvalu.

This is the default code set.

alpha-3, LOCALE_CODE_ALPHA_3

This is the set of three-letter (lowercase) codes from ISO 3166-1, such as 'brb' for Barbados. These codes are actually defined and maintained by the U.N. Statistics division.

numeric, LOCALE_CODE_NUMERIC

This is the set of three-digit numeric codes from ISO 3166-1, such as 064 for Bhutan. These codes are actually defined and maintained by the U.N. Statistics division.

If a 2-digit code is entered, it is converted to 3 digits by prepending a 0.

dom, LOCALE_CODE_DOM

The IANA is responsible for delegating management of the top level country domains. The country domains are the two-letter (lowercase) codes from ISO 3166 with a few other additions.

NOTE: As of version 3.27, the FIPS code set is no longer supported. See the Locale::Codes::Changes document for details.

ROUTINES

code2country(CODE [,CODESET] [,'retired'])
country2code(NAME [,CODESET] [,'retired'])
country_code2code(CODE ,CODESET ,CODESET2)
all_country_codes([CODESET] [,'retired'])
all_country_names([CODESET] [,'retired'])
Locale::Codes::Country::rename_country(CODE ,NEW_NAME [,CODESET])
Locale::Codes::Country::add_country(CODE ,NAME [,CODESET])
Locale::Codes::Country::delete_country(CODE [,CODESET])
Locale::Codes::Country::add_country_alias(NAME ,NEW_NAME)
Locale::Codes::Country::delete_country_alias(NAME)
Locale::Codes::Country::rename_country_code(CODE ,NEW_CODE [,CODESET])
Locale::Codes::Country::add_country_code_alias(CODE ,NEW_CODE [,CODESET])
Locale::Codes::Country::delete_country_code_alias(CODE [,CODESET])

These routines are all documented in the Locale::Codes::API man page.

alias_code ( ALIAS, CODE [,CODESET] )

Version 2.07 included 2 functions for modifying the internal data: rename_country and alias_code. Both of these could be used only to modify the internal data for country codes.

As of 3.10, the internal data for all types of codes can be modified.

The alias_code function is preserved for backwards compatibility, but the following two are identical:

alias_code(ALIAS,CODE [,CODESET]);
rename_country_code(CODE,ALIAS [,CODESET]);

and the latter should be used for consistency.

The alias_code function is deprecated and will be removed in the December 2014 release.

Note: this function was previously called _alias_code, but the leading underscore has been dropped. The old name was supported for all 2.X releases, but has been dropped as of 3.00.

The World Factbook maintained by the CIA is a potential source of the data. Unfortunately, it adds/preserves non-standard codes, so it is no longer used as a source of data.

Another unofficial source of data. Currently, it is not used to get data, but the notes and explanatory material were very useful for understanding discrepancies between the sources.
