Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: postgresql (UTSA-2026-104766)

high Nessus Plugin ID 340946

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-2026-104766 advisory.

Type confusion regarding input of PostgreSQL ctid data type selectivity estimator allows an object creator to view a calculation derived from the value of an arbitrary 4-byte span of memory, via a chosen non-ctid input. While the calculation loses precision, substantial memory value recovery appears possible.
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.
