Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Improper validation of type "oidvector" in PostgreSQL allows a database user to disclose a few bytes of
 server memory. We have not ruled out viability of attacks that arrange for presence of confidential
 information in disclosed bytes, but they seem unlikely. Versions before PostgreSQL 18.2, 17.8, 16.12,
 15.16, and 14.21 are affected. (CVE-2026-2003)

Solution

Update the postgresql-15 library and its related packages to version 15.16 or later.
