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-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

NAME

TAP::Object - Base class that provides common functionality to all TAP::* modules

VERSION

Version 3.42

SYNOPSIS

package TAP::Whatever;

use strict;

use base 'TAP::Object';

# new() implementation by TAP::Object
sub _initialize {
    my ( $self, @args) = @_;
    # initialize your object
    return $self;
}

# ... later ...
my $obj = TAP::Whatever->new(@args);

DESCRIPTION

TAP::Object provides a default constructor and exception model for all TAP::* classes. Exceptions are raised using Carp.

METHODS

Class Methods

new

Create a new object. Any arguments passed to new will be passed on to the "_initialize" method. Returns a new object.

Instance Methods

_initialize

Initializes a new object. This method is a stub by default, you should override it as appropriate.

Note: "new" expects you to return $self or raise an exception. See "_croak", and Carp.

_croak

Raise an exception using croak from Carp, eg:

$self->_croak( 'why me?', 'aaarrgh!' );

May also be called as a class method.

$class->_croak( 'this works too' );

_confess

Raise an exception using confess from Carp, eg:

$self->_confess( 'why me?', 'aaarrgh!' );

May also be called as a class method.

$class->_confess( 'this works too' );

_construct

Create a new instance of the specified class.

mk_methods

Create simple getter/setters.
