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

high Tenable Cloud Security Plugin ID 461045

Description

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

 - IO::Uncompress::Unzip versions before 2.220 for Perl allow CPU exhaustion via per-byte read loop in
 fastForward. fastForward() compares length $offset (the digit count of the offset, 1 to 19) against the
 chunk size $c instead of $offset itself, so $c shrinks from 16 KiB to 1-19 bytes per iteration. Extracting
 a named entry from an attacker supplied zip via IO::Uncompress::Unzip->new($zip, Name => $target) drives a
 per-byte read loop scaling with the entry's compressed size, up to the non-Zip64 4 GiB cap.
 (CVE-2026-48959)

Solution

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