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

mkppport - distribute ppport.h among extensions

SYNOPSIS

mkppport [--list=file] [--clean]

DESCRIPTION

mkppport generates a ppport.h file using Devel::PPPort and distributes it to the various extension directories that need it to build. On certain Win32 builds, this script is not used and an alternative mechanism is used to create ppport.h.

OPTIONS

--list=file

Name of the file that holds the list of extension directories that ppport.h should be distributed to. This defaults to mkppport.lst in the same directory as this script.

--clean

Run with this option to clean out all distributed ppport.h files.
