Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: postgresql (UTSA-2026-104773)

low Nessus Plugin ID 340909

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-2026-104773 advisory.

Integer underflow in PostgreSQL ECPG allows a database server administrator to achieve temporary denial of service against the ECPG client via sending a bytea value lacking the mandatory prefix. The client overwrites a huge memory region with bytes outside attacker knowledge or control. This typically yields a simple SIGSEGV, but rare cases might achieve client-specific integrity impact via the write. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

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 postgresql package.
