critical Nessus Plugin ID 373776

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-147046 advisory.

DBI versions before 1.650 for Perl have a heap overflow when preparsing SQL statements with an extreme number of placeholders.

The fix for CVE-2026-10879 did not allocate enough memory to handle approximately 1.2-million placeholders.

DBI version 1.650 sets a hard limit of 99,999 placeholders.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected perl-DBI package.
