Synopsis

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

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8072-1 advisory.

 Altan Birler discovered that PostgreSQL incorrectly validated oidvector types. An attacker could possibly use this issue to obtain a few bytes of sensitive information. (CVE-2026-2003)

 Daniel Firer discovered that PostgreSQL incorrectly validated input in the intarray extension. An attacker could possibly use this issue to execute arbitrary code. (CVE-2026-2004)

 It was dicovered that PosgreSQL incorrectly handled certain pgcrypto memory operations. An attacker could possibly use this issue to execute arbitrary code. (CVE-2026-2005)

 Paul Gerste and Moritz Sanft discovered that PostgreSQL incorrectly validated multibyte character lengths.
 An attacker could possibly use this issue to execute arbitrary code. (CVE-2026-2006)

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

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