Synopsis

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

Description

This update for the Linux Kernel 4.4.103-92_56 fixes several issues.

The following security issues were fixed :

CVE-2018-5390: Prevent very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming TCP packet which can lead to a denial of service (bsc#1102682).

CVE-2018-1000026: Fixed an insufficient input validation in bnx2x network card driver that can result in DoS via very large, specially crafted packet to the bnx2x card due to a network card firmware assertion that will take the card offline (bsc#1096723).

CVE-2018-10938: Fixed an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service via crafted network packets (bsc#1106191).

CVE-2018-10902: It was found that the raw midi kernel driver did not protect against concurrent access which lead to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(), allowing a malicious local attacker to use this for privilege escalation (bsc#1105323).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
