medium Nessus Plugin ID 343947

Synopsis

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

Description

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21783-1 advisory.

 - CVE-2026-23679: NULL pointer dereference in `parse_interface()` allows attackers to crash applications by supplying a malformed USB configuration descriptor (bsc#1266664).
 - CVE-2026-47104: one-byte out-of-bounds read in `parse_iad_array()` allows attackers to trigger a denial of service via a malformed USB descriptor (bsc#1266667).

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
