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

critical Tenable Self-Hosted Container Security Plugin ID 463163

Description

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

 - Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK
 record. retrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend
 with that count plus one. A count of I32_MAX wraps the addition to a negative value. A crafted blob passed
 to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic,
 terminating the deserialization. (CVE-2026-57433)

Solution

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