medium Nessus Plugin ID 331665

Synopsis

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

Description

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21506-1 advisory.

- CVE-2026-57965: integer overflow in `udscs_write()` allows a compromised SPICE host to crash the `spice- vdagent` daemon via a specially crafted message that triggers a heap buffer overflow (bsc#1269553).
- CVE-2026-57966: improper sanitization allows a compromised SPICE host to write arbitrary files to any location on the guest operating system (bsc#1269554).

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

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

Solution

Update the affected spice-vdagent package.
