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.

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.

NAME

TAP::Parser::Iterator::Array - Iterator for array-based TAP sources

VERSION

Version 3.50

SYNOPSIS

use TAP::Parser::Iterator::Array;
my @data = ('foo', 'bar', baz');
my $it   = TAP::Parser::Iterator::Array->new(\@data);
my $line = $it->next;

DESCRIPTION

This is a simple iterator wrapper for arrays of scalar content, used by TAP::Parser. Unless you're writing a plugin or subclassing, you probably won't need to use this module directly.

METHODS

Class Methods

new

Create an iterator. Takes one argument: an $array_ref

Instance Methods

next

Iterate through it, of course.

next_raw

Iterate raw input without applying any fixes for quirky input syntax.

wait

Get the wait status for this iterator. For an array iterator this will always be zero.

exit

Get the exit status for this iterator. For an array iterator this will always be zero.
