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

  - GStreamer H.266 Codec Parser Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability     allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with     this library is required to exploit this vulnerability but attack vectors may vary depending on the     implementation. The specific flaw exists within the processing of APS units. The issue results from the     lack of proper validation of user-supplied data, which can result in a write past the end of an allocated     buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
    Was ZDI-CAN-28911. (CVE-2026-3086)

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

The remote Debian 12 / 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6190 advisory.
