FreeBSD : FreeBSD -- Remote denial of service in IPv6 fragment reassembly (3dabf5b8-47c0-11ee-8e38-002590c1f29c)

high Nessus Plugin ID 180338

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 3dabf5b8-47c0-11ee-8e38-002590c1f29c advisory.

 - A set of carefully crafted ipv6 packets can trigger an integer overflow in the calculation of a fragment reassembled packet's payload length field. This allows an attacker to trigger a kernel panic, resulting in a denial of service. (CVE-2023-3107)

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

Solution

Update the affected packages.
