Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5553 advisory.

Several vulnerabilities have been discovered in the PostgreSQL database system. CVE-2023-5868 Jingzhou Fu discovered a memory disclosure flaw in aggregate function calls. CVE-2023-5869 Pedro Gallegos reported integer overflow flaws resulting in buffer overflows in the array modification functions. CVE-2023-5870 Hemanth Sandrana and Mahendrakar Srinivasarao reported that the pg_cancel_backend role can signal certain superuser processes, potentially resulting in denial of service. CVE-2023-39417 Micah Gate, Valerie Woolard, Tim Carey-Smith, and Christoph Berg reported that an extension script using @substitutions@ within quoting may allow to perform an SQL injection for an attacker having database-level CREATE privileges. CVE-2023-39418 Dean Rasheed reported that the MERGE command fails to enforce UPDATE or SELECT row security policies. For the stable distribution (bookworm), these problems have been fixed in version 15.5-0+deb12u1. We recommend that you upgrade your postgresql-15 packages. For the detailed security status of postgresql-15 please refer to its security tracker page at: https://security- tracker.debian.org/tracker/postgresql-15
