SUSE SLES12 Security Update : kernel (SUSE-SU-2018:3787-1)
High Nessus Plugin ID 119033
SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionThis update for the Linux Kernel 4.4.103-92_56 fixes several issues.
The following security issues were fixed :
CVE-2018-5391: Fixed a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may have caused a denial of service condition by sending specially crafted IP fragments. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bsc#1103098).
CVE-2018-18386: The drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bsc#1112039).
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.
