Synopsis

The remote Red Hat host is missing a security update for postgresql16-postgis.

Description

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:65899 advisory.

 PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS spatially enables the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS Simple Features Specification for SQL and has been certified as compliant with the Types and Functions profile.

 Security Fix(es):

 * postgis: PostGIS: Memory Disclosure and Denial of Service via Malformed FlatGeobuf Buffer (CVE-2026-73515)

 For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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 RHEL postgresql16-postgis package based on the guidance in RHSA-2026:65899.
