   An update that fixes one vulnerability is now available.

Description:



   The SUSE Linux Enterprise 11 SP3 kernel was updated to fix the following
   security bug:

   CVE-2017-2636: A race condition in the n_hdlc tty Linux kernel driver
   (drivers/tty/n_hdlc.c) could have been exploited to gain a local privilege
   escalation (bnc#1027565)


Patch Instructions:

   To install this SUSE Security Update use YaST online_update.
   Alternatively you can run the command listed for your product:

   - SUSE OpenStack Cloud 5:
