high Nessus Plugin ID 193245

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 / SLES15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2024:1207-1 advisory.

- When a router encounters an IPv6 packet too big to transmit to the next-hop, it returns an ICMP6 Packet Too Big (PTB) message to the sender. The sender caches this updated Maximum Transmission Unit (MTU) so it knows not to exceed this value when subsequently routing to the same host. (CVE-2023-52340)

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 kernel-livepatch-5_3_18-150200_24_178-default, kernel-livepatch-5_3_18-150300_59_150-default and / or kgraft-patch-4_12_14-122_194-default packages.
