Echo: perl: security update to 5.40.1-6+e6

high Tenable Self-Hosted Container Security Plugin ID 464863

Description

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

 - Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size
 field in tar header. _read_tar() reads each entry's payload with $handle->read($$data, $block), where
 $block is derived from the entry's 12-byte size field in the tar header with no upper bound on that value.
 A crafted header declaring a multi-gigabyte size causes Perl to allocate a scalar of that size.
 (CVE-2026-9538)

Solution

Update the perl library and its related packages to version 5.40.1-6+e6 or later.
