SUSE SLES16 Security Update : postgresql17 and postgresql18 (SUSE-SU-2026:20194-1)

medium Nessus Plugin ID 297843

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES16 / SLES_SAP16 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:20194-1 advisory.

 Changes in postgresql17, postgresql18:

 Update to 17.7:

 * https://www.postgresql.org/about/news/p-3171/
 * https://www.postgresql.org/docs/release/17.7/

 * bsc#1253332, CVE-2025-12817: Missing check for CREATE privileges on the schema in CREATE STATISTICS allowed table owners to create statistics in any schema, potentially leading to unexpected naming conflicts.
 * bsc#1253333, CVE-2025-12818: Several places in libpq were not sufficiently careful about computing the required size of a memory allocation. Sufficiently large inputs could cause integer overflow, resulting in an undersized buffer, which would then lead to writing past the end of the buffer.


 Postgresql is shipped in version 18.1.

 pgvector was updated to 0.8.1 to support postgresql18.

 pgaudit was updated to support postgresql18.

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

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

Solution

Update the affected packages.
