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-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-2017-12814 (2017-09-28)

Stack-based buffer overflow in the CPerlHost::Add method in win32/perlhost.h in Perl before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 on Windows allows attackers to execute arbitrary code via a long environment variable.

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-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-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-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-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-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-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-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.

NAME

TAP::Parser::Aggregator - Aggregate TAP::Parser results

VERSION

Version 3.36

SYNOPSIS

use TAP::Parser::Aggregator;

my $aggregate = TAP::Parser::Aggregator->new;
$aggregate->add( 't/00-load.t', $load_parser );
$aggregate->add( 't/10-lex.t',  $lex_parser  );

my $summary = <<'END_SUMMARY';
Passed:  %s
Failed:  %s
Unexpectedly succeeded: %s
END_SUMMARY
printf $summary,
       scalar $aggregate->passed,
       scalar $aggregate->failed,
       scalar $aggregate->todo_passed;

DESCRIPTION

TAP::Parser::Aggregator collects parser objects and allows reporting/querying their aggregate results.

METHODS

Class Methods

new

my $aggregate = TAP::Parser::Aggregator->new;

Returns a new TAP::Parser::Aggregator object.

Instance Methods

add

$aggregate->add( $description => $parser );

The $description is usually a test file name (but only by convention.) It is used as a unique identifier (see e.g. "parsers".) Reusing a description is a fatal error.

The $parser is a TAP::Parser object.

parsers

my $count   = $aggregate->parsers;
my @parsers = $aggregate->parsers;
my @parsers = $aggregate->parsers(@descriptions);

In scalar context without arguments, this method returns the number of parsers aggregated. In list context without arguments, returns the parsers in the order they were added.

If @descriptions is given, these correspond to the keys used in each call to the add() method. Returns an array of the requested parsers (in the requested order) in list context or an array reference in scalar context.

Requesting an unknown identifier is a fatal error.

descriptions

Get an array of descriptions in the order in which they were added to the aggregator.

start

Call start immediately before adding any results to the aggregator. Among other times it records the start time for the test run.

stop

Call stop immediately after adding all test results to the aggregator.

elapsed

Elapsed returns a Benchmark object that represents the running time of the aggregated tests. In order for elapsed to be valid you must call start before running the tests and stop immediately afterwards.

elapsed_timestr

Returns a formatted string representing the runtime returned by elapsed(). This lets the caller not worry about Benchmark.

all_passed

Return true if all the tests passed and no parse errors were detected.

get_status

Get a single word describing the status of the aggregated tests. Depending on the outcome of the tests returns 'PASS', 'FAIL' or 'NOTESTS'. This token is understood by CPAN::Reporter.

Summary methods

Each of the following methods will return the total number of corresponding tests if called in scalar context. If called in list context, returns the descriptions of the parsers which contain the corresponding tests (see add for an explanation of description.

  • failed

  • parse_errors

  • passed

  • planned

  • skipped

  • todo

  • todo_passed

  • wait

  • exit

For example, to find out how many tests unexpectedly succeeded (TODO tests which passed when they shouldn't):

my $count        = $aggregate->todo_passed;
my @descriptions = $aggregate->todo_passed;

Note that wait and exit are the totals of the wait and exit statuses of each of the tests. These values are totalled only to provide a true value if any of them are non-zero.

total

my $tests_run = $aggregate->total;

Returns the total number of tests run.

has_problems

if ( $parser->has_problems ) {
    ...
}

Identical to has_errors, but also returns true if any TODO tests unexpectedly succeeded. This is more akin to "warnings".

has_errors

if ( $parser->has_errors ) {
    ...
}

Returns true if any of the parsers failed. This includes:

  • Failed tests

  • Parse errors

  • Bad exit or wait status

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.
