Security Advisories (17)
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-2018-6913 (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)

Perl before 5.26.3 has a buffer overflow via a crafted regular expression that triggers invalid write operations.

CVE-2018-18313 (2018-12-07)

Perl before 5.26.3 has a buffer over-read via a crafted regular expression that triggers disclosure of sensitive information from process memory.

CVE-2018-18312 (2018-12-05)

Perl before 5.26.3 and 5.28.0 before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.

CVE-2018-18311 (2018-12-07)

Perl before 5.26.3 and 5.28.x before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.

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-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-2016-2381 (2016-04-08)

Perl might allow context-dependent attackers to bypass the taint protection mechanism in a child process via duplicate environment variables in envp.

CVE-2013-7422 (2015-08-16)

Integer underflow in regcomp.c in Perl before 5.20, as used in Apple OS X before 10.10.5 and other products, allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via a long digit string associated with an invalid backreference within a regular expression.

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

TAP::Parser::Result::Test - Test result token.

VERSION

Version 3.26

DESCRIPTION

This is a subclass of TAP::Parser::Result. A token of this class will be returned if a test line is encountered.

1..1
ok 1 - woo hooo!

OVERRIDDEN METHODS

This class is the workhorse of the TAP::Parser system. Most TAP lines will be test lines and if $result->is_test, then you have a bunch of methods at your disposal.

Instance Methods

ok

my $ok = $result->ok;

Returns the literal text of the ok or not ok status.

number

my $test_number = $result->number;

Returns the number of the test, even if the original TAP output did not supply that number.

description

my $description = $result->description;

Returns the description of the test, if any. This is the portion after the test number but before the directive.

directive

my $directive = $result->directive;

Returns either TODO or SKIP if either directive was present for a test line.

explanation

my $explanation = $result->explanation;

If a test had either a TODO or SKIP directive, this method will return the accompanying explanation, if present.

not ok 17 - 'Pigs can fly' # TODO not enough acid

For the above line, the explanation is not enough acid.

is_ok

if ( $result->is_ok ) { ... }

Returns a boolean value indicating whether or not the test passed. Remember that for TODO tests, the test always passes.

If the test is unplanned, this method will always return false. See is_unplanned.

is_actual_ok

if ( $result->is_actual_ok ) { ... }

Returns a boolean value indicating whether or not the test passed, regardless of its TODO status.

actual_passed

Deprecated. Please use is_actual_ok instead.

todo_passed

if ( $test->todo_passed ) {
   # test unexpectedly succeeded
}

If this is a TODO test and an 'ok' line, this method returns true. Otherwise, it will always return false (regardless of passing status on non-todo tests).

This is used to track which tests unexpectedly succeeded.

todo_failed

# deprecated in favor of 'todo_passed'.  This method was horribly misnamed.

This was a badly misnamed method. It indicates which TODO tests unexpectedly succeeded. Will now issue a warning and call todo_passed.

has_skip

if ( $result->has_skip ) { ... }

Returns a boolean value indicating whether or not this test has a SKIP directive.

has_todo

if ( $result->has_todo ) { ... }

Returns a boolean value indicating whether or not this test has a TODO directive.

as_string

print $result->as_string;

This method prints the test as a string. It will probably be similar, but not necessarily identical, to the original test line. Directives are capitalized, some whitespace may be trimmed and a test number will be added if it was not present in the original line. If you need the original text of the test line, use the raw method.

is_unplanned

if ( $test->is_unplanned ) { ... }
$test->is_unplanned(1);

If a test number is greater than the number of planned tests, this method will return true. Unplanned tests will always return false for is_ok, regardless of whether or not the test has_todo.

Note that if tests have a trailing plan, it is not possible to set this property for unplanned tests as we do not know it's unplanned until the plan is reached:

print <<'END';
ok 1
ok 2
1..1
