SUSE Security Update: Security update for the Linux Kernel (Live Patch 0 for SLE 15)
______________________________________________________________________________
Announcement ID: SUSE-SU-2018:3880-1
Rating: important
References: #1103098 #1112039
Cross-References: CVE-2018-18386 CVE-2018-5391
Affected Products:
SUSE Linux Enterprise Module for Live Patching 15
______________________________________________________________________________
An update that fixes two vulnerabilities is now available.
Description:
This update for the Linux Kernel 4.12.14-23 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).
