CVE-2026-4176 (2026-03-29)

Perl versions from 5.9.4 before 5.40.4-RC1, from 5.41.0 before 5.42.2-RC1, from 5.43.0 before 5.43.9 contain a vulnerable version of Compress::Raw::Zlib. Compress::Raw::Zlib is included in the Perl package as a dual-life core module, and is vulnerable to CVE-2026-3381 due to a vendored version of zlib which has several vulnerabilities, including CVE-2026-27171. The bundled Compress::Raw::Zlib was updated to version 2.221 in Perl blead commit c75ae9cc164205e1b6d6dbd57bd2c65c8593fe94.

CVE-2026-8376 (2026-05-25)

Perl versions through 5.43.10 have a heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds. Perl_study_chunk in regcomp_study.c checked the size of the joined substring buffer in characters rather than bytes. For a quantified fixed substring with a large minimum count, the byte length mincount * l could overflow SSize_t, producing an undersized SvGROW allocation; the subsequent copy writes past the end of the buffer. A caller that compiles an attacker-controlled regular expression on a 32-bit perl build triggers a heap buffer overflow at compile time.

NAME

Getopt::Long::Parser - Getopt::Long object-oriented interface

SYNOPSIS

use Getopt::Long::Parser;
my $p = Getopt::Long::Parser->new;
$p->configure( %options );
if ( $p->getoptions( @options ) ) { ... }
if ( $p->getoptionsfromarray( \@array, @options ) ) { ... }

Configuration options can be passed to the constructor:

my $p = Getopt::Long::Parser->new( config => [ %options ] );

DESCRIPTION

Getopt::Long::Parser is an object-oriented interface to Getopt::Long. See its documentation for configuration and use.

Note that Getopt::Long and Getopt::Long::Parser are not object-oriented. Getopt::Long::Parser emulates an object-oriented interface, which should be okay for most purposes.

CONSTRUCTOR

my $p = Getopt::Long::Parser->new( %options );

The constructor takes an optional hash with parameters.

config

An array reference with configuration settings. See "Configuring Getopt::Long" in Getopt::Long for all possible settings.

METHODS

In the examples, $p is assumed to be the result of a call to the constructor.

configure

$p->configure( %settings );

Update the current config settings. See "Configuring Getopt::Long" in Getopt::Long for all possible settings.

getoptionsfromarray

my $res = $p->getoptionsfromarray( $aref, @opts );

getoptions

my $res = $p->getoptions( @opts );

The same as getoptionsfromarray( \@ARGV, @opts ).
