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

high Tenable Self-Hosted Container Security Plugin ID 459089

Description

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

- Perl versions before 5.40.5-RC1, from 5.41.0 before 5.42.3-RC1, from 5.43.0 before 5.43.11 have an integer
overflow in S_measure_struct leading to an out-of-bounds heap read in pack and unpack. S_measure_struct
adds each item's size times its repeat count to a running total with no overflow check, so a large repeat
count in a pack or unpack template wraps the signed SSize_t total negative. The @, X, and x position codes
then guard their moves with a signed length comparison that passes when the length is negative, advancing
the buffer pointer out of bounds. A template derived from untrusted input can read heap memory past the
buffer and return it to the caller. (CVE-2026-57432)

Solution

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