high Nessus Plugin ID 300972

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2026:0785-1 advisory.

 This update for postgresql18 fixes the following issue:

 Update to version 18.3 (bsc#1258754).

 Regression fixes:

 - the substring() function raises an error 'invalid byte sequence for encoding' on non-ASCII text values if the source of that value is a database column (caused by CVE-2026-2006 fix).
 - a standby may halt and return an error 'could not access status of transaction'.

Tenable has extracted the preceding description block directly from the SUSE 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 libecpg6, libecpg6-32bit, libpq5 and / or libpq5-32bit packages.
