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

high Tenable Self-Hosted Container Security Plugin ID 463166

Description

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

 - IO::Compress versions from 2.207 before 2.220 for Perl ship a zipdetails CLI tool that crashes with
 undefined subroutine on Info-ZIP Unix Extra Field with 8-byte UID or GID. When decode_ux() in
 bin/zipdetails handles an Info-ZIP Unix Extra Field (tag 0x7875) with UID Size or GID Size set to 8,
 causing zipdetails to decode an 8-byte UID or GID value, it dispatches through decodeLitteEndian(), which
 calls a misnamed helper unpackValueQ. The actual function defined in the same file is unpackValue_Q (with
 underscore); the call raises 'Undefined subroutine &main::unpackValueQ' and the script exits with status
 255. Library callers of IO::Compress and IO::Uncompress are not affected; the defect is in the bundled CLI
 tool. (CVE-2026-48961)

Solution

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