Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to     issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the     operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21     are affected. (CVE-2026-2006)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6132 advisory.
