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)

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-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

TAP::Parser::Scheduler - Schedule tests during parallel testing

VERSION

Version 3.35

SYNOPSIS

use TAP::Parser::Scheduler;

DESCRIPTION

METHODS

Class Methods

new

my $sched = TAP::Parser::Scheduler->new(tests => \@tests);
my $sched = TAP::Parser::Scheduler->new(
    tests => [ ['t/test_name.t','Test Description'], ... ],
    rules => \%rules,
);

Given 'tests' and optional 'rules' as input, returns a new TAP::Parser::Scheduler object. Each member of @tests should be either a a test file name, or a two element arrayref, where the first element is a test file name, and the second element is a test description. By default, we'll use the test name as the description.

The optional rules attribute provides direction on which tests should be run in parallel and which should be run sequentially. If no rule data structure is provided, a default data structure is used which makes every test eligible to be run in parallel:

{ par => '**' },

The rules data structure is documented more in the next section.

Rules data structure

The "rules" data structure is the the heart of the scheduler. It allows you to express simple rules like "run all tests in sequence" or "run all tests in parallel except these five tests.". However, the rules structure also supports glob-style pattern matching and recursive definitions, so you can also express arbitarily complicated patterns.

The rule must only have one top level key: either 'par' for "parallel" or 'seq' for "sequence".

Values must be either strings with possible glob-style matching, or arrayrefs of strings or hashrefs which follow this pattern recursively.

Every element in an arrayref directly below a 'par' key is eligible to be run in parallel, while vavalues directly below a 'seq' key must be run in sequence.

Rules examples

Here are some examples:

# All tests be run in parallel (the default rule)
{ par => '**' },

# Run all tests in sequence, except those starting with "p"
{ par => 't/p*.t' },

# Run all tests in parallel, except those starting with "p"
{
    seq => [
              { seq => 't/p*.t' },
              { par => '**'     },
           ],
}

# Run some  startup tests in sequence, then some parallel tests than some
# teardown tests in sequence.
{
    seq => [
        { seq => 't/startup/*.t' },
        { par => ['t/a/*.t','t/b/*.t','t/c/*.t'], }
        { seq => 't/shutdown/*.t' },
    ],
},

Rules resolution

  • By default, all tests are eligible to be run in parallel. Specifying any of your own rules removes this one.

  • "First match wins". The first rule that matches a test will be the one that applies.

  • Any test which does not match a rule will be run in sequence at the end of the run.

  • The existence of a rule does not imply selecting a test. You must still specify the tests to run.

  • Specifying a rule to allow tests to run in parallel does not make the run in parallel. You still need specify the number of parallel jobs in your Harness object.

Glob-style pattern matching for rules

We implement our own glob-style pattern matching. Here are the patterns it supports:

** is any number of characters, including /, within a pathname
* is zero or more characters within a filename/directory name
? is exactly one character within a filename/directory name
{foo,bar,baz} is any of foo, bar or baz.
\ is an escape character

Instance Methods

get_all

Get a list of all remaining tests.

get_job

Return the next available job as TAP::Parser::Scheduler::Job object or undef if none are available. Returns a TAP::Parser::Scheduler::Spinner if the scheduler still has pending jobs but none are available to run right now.

as_string

Return a human readable representation of the scheduling tree. For example:

my @tests = (qw{
    t/startup/foo.t 
    t/shutdown/foo.t

    t/a/foo.t t/b/foo.t t/c/foo.t t/d/foo.t
});
my $sched = TAP::Parser::Scheduler->new(
    tests => \@tests,
    rules => {
        seq => [
            { seq => 't/startup/*.t' },
            { par => ['t/a/*.t','t/b/*.t','t/c/*.t'] },
            { seq => 't/shutdown/*.t' },
        ],
    },
);

Produces:

par:
  seq:
    par:
      seq:
        par:
          seq:
            't/startup/foo.t'
        par:
          seq:
            't/a/foo.t'
          seq:
            't/b/foo.t'
          seq:
            't/c/foo.t'
        par:
          seq:
            't/shutdown/foo.t'
    't/d/foo.t'
