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.
