Echo: perl: security update to 5.40.1-6+e18

high Tenable Self-Hosted Container Security Plugin ID 462790

Description

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

 - Archive::Tar versions before 3.08 for Perl extract hardlinks to attacker controlled paths outside the
 extraction directory. _make_special_file() passes the tar header's linkname to link() without validating
 it against absolute paths or .. segments, creating a hardlink that shares the victim file's inode. A
 subsequent write through the extracted name modifies the victim file, and the post-extraction chmod,
 chown, and utime block in _extract_file() (guarded only against symlinks via -l) applies the tar header's
 mode, owner, and timestamps to the shared inode during extraction alone. (CVE-2026-42497)

Solution

Update the perl library and its related packages to version 5.40.1-6+e18 or later.
