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

Pod::Simple::PullParserStartToken -- start-tokens from Pod::Simple::PullParser

SYNOPSIS

(See Pod::Simple::PullParser)

DESCRIPTION

When you do $parser->get_token on a Pod::Simple::PullParser object, you might get an object of this class.

This is a subclass of Pod::Simple::PullParserToken and inherits all its methods, and adds these methods:

$token->tagname

This returns the tagname for this start-token object. For example, parsing a "=head1 ..." line will give you a start-token with the tagname of "head1", token(s) for its content, and then an end-token with the tagname of "head1".

$token->tagname(somestring)

This changes the tagname for this start-token object. You probably won't need to do this.

$token->tag(...)

A shortcut for $token->tagname(...)

$token->is_tag(somestring) or $token->is_tagname(somestring)

These are shortcuts for $token->tag() eq somestring

$token->attr(attrname)

This returns the value of the attrname attribute for this start-token object, or undef.

For example, parsing a L<Foo/"Bar"> link will produce a start-token with a "to" attribute with the value "Foo", a "type" attribute with the value "pod", and a "section" attribute with the value "Bar".

$token->attr(attrname, newvalue)

This sets the attrname attribute for this start-token object to newvalue. You probably won't need to do this.

$token->attr_hash

This returns the hashref that is the attribute set for this start-token. This is useful if (for example) you want to ask what all the attributes are -- you can just do keys %{$token->attr_hash}

You're unlikely to ever need to construct an object of this class for yourself, but if you want to, call Pod::Simple::PullParserStartToken->new( tagname, attrhash )
