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-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::Functions - Group Perl's functions a la perlfunc.pod

SYNOPSIS

use Pod::Functions;

my @misc_ops = @{ $Kinds{ 'Misc' } };
my $misc_dsc = $Type_Description{ 'Misc' };

or

perl /path/to/lib/Pod/Functions.pm

This will print a grouped list of Perl's functions, like the "Perl Functions by Category" in perlfunc section.

DESCRIPTION

It exports the following variables:

%Kinds

This holds a hash-of-lists. Each list contains the functions in the category the key denotes.

%Type

In this hash each key represents a function and the value is the category. The category can be a comma separated list.

%Flavor

In this hash each key represents a function and the value is a short description of that function.

%Type_Description

In this hash each key represents a category of functions and the value is a short description of that category.

@Type_Order

This list of categories is used to produce the same order as the "Perl Functions by Category" in perlfunc section.
