Echo: perl: security update to 5.36.0-7+deb12u2-e0

medium Tenable Cloud Security Plugin ID 461060

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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-2025-40909)

Solution

Update the perl library and its related packages to version 5.36.0-7+deb12u2-e0 or later.
