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-2013-1667 (2013-03-14)

The rehash mechanism in Perl 5.8.2 through 5.16.x allows context-dependent attackers to cause a denial of service (memory consumption and crash) via a crafted hash key.

CVE-2010-4777 (2014-02-10)

The Perl_reg_numbered_buff_fetch function in Perl 5.10.0, 5.12.0, 5.14.0, and other versions, when running with debugging enabled, allows context-dependent attackers to cause a denial of service (assertion failure and application exit) via crafted input that is not properly handled when using certain regular expressions, as demonstrated by causing SpamAssassin and OCSInventory to crash.

CVE-2010-1158 (2010-04-20)

Integer overflow in the regular expression engine in Perl 5.8.x allows context-dependent attackers to cause a denial of service (stack consumption and application crash) by matching a crafted regular expression against a long string.

CVE-2009-3626 (2009-10-29)

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-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-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

CPANPLUS::Configure

SYNOPSIS

$conf   = CPANPLUS::Configure->new( );

$bool   = $conf->can_save;
$bool   = $conf->save( $where );

@opts   = $conf->options( $type );

$make       = $conf->get_program('make');
$verbose    = $conf->set_conf( verbose => 1 );

DESCRIPTION

This module deals with all the configuration issues for CPANPLUS. Users can use objects created by this module to alter the behaviour of CPANPLUS.

Please refer to the CPANPLUS::Backend documentation on how to obtain a CPANPLUS::Configure object.

METHODS

$Configure = CPANPLUS::Configure->new( load_configs => BOOL )

This method returns a new object. Normal users will never need to invoke the new method, but instead retrieve the desired object via a method call on a CPANPLUS::Backend object.

The load_configs parameter controls wether or not additional user configurations are to be loaded or not. Defaults to true.

$bool = $Configure->init( [rescan => BOOL])

Initialize the configure with other config files than just the default 'CPANPLUS::Config'.

Called from new() to load user/system configurations

If the rescan option is provided, your disk will be examined again to see if there are new config files that could be read. Defaults to false.

Returns true on success, false on failure.

can_save( [$config_location] )

Check if we can save the configuration to the specified file. If no file is provided, defaults to your personal config.

Returns true if the file can be saved, false otherwise.

$file = $conf->save( [$package_name] )

Saves the configuration to the package name you provided. If this package is not CPANPLUS::Config::System, it will be saved in your .cpanplus directory, otherwise it will be attempted to be saved in the system wide directory.

If no argument is provided, it will default to your personal config.

Returns the full path to the file if the config was saved, false otherwise.

options( type => TYPE )

Returns a list of all valid config options given a specific type (like for example conf of program) or false if the type does not exist

ACCESSORS

Accessors that start with a _ are marked private -- regular users should never need to use these.

See the CPANPLUS::Config documentation for what items can be set and retrieved.

get_SOMETHING( ITEM, [ITEM, ITEM, ... ] );

The get_* style accessors merely retrieves one or more desired config options.

set_SOMETHING( ITEM => VAL, [ITEM => VAL, ITEM => VAL, ... ] );

The set_* style accessors set the current value for one or more config options and will return true upon success, false on failure.

add_SOMETHING( ITEM => VAL, [ITEM => VAL, ITEM => VAL, ... ] );

The add_* style accessor adds a new key to a config key.

Currently, the following accessors exist:

set|get_conf

Simple configuration directives like verbosity and favourite shell.

set|get_program

Location of helper programs.

_set|_get_build

Locations of where to put what files for CPANPLUS.

_set|_get_source

Locations and names of source files locally.

_set|_get_mirror

Locations and names of source files remotely.

_set|_get_dist

Mapping of distribution format names to modules.

_set|_get_fetch

Special settings pertaining to the fetching of files.

_set|_get_daemon

Settings for cpanpd, the CPANPLUS daemon.
