high Nessus Plugin ID 307660

Synopsis

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

Description

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-0a7ed21996 advisory.

 This update addresses two security issues regarding incorrect handling of malformed IPv6 addresses:

 * Fix IPv4 mapped IPv6 packed length (CVE-2026-40199)
 * Reject invalid uncompressed IPv6 (CVE-2026-40198)

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

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