An update that solves two vulnerabilities and has one security fix can now be installed.

Description:

The SUSE Linux Enterprise 12 kernel was updated to fix the following security bugs:

• CVE-2017-7184: The Linux kernel allowed local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) via unspecified vectors, as demonstrated during a Pwn2Own competition at CanSecWest 2017 (bnc#1030573, bnc#1028372).
• CVE-2017-2636: Race condition in drivers/tty/n_hdlc.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline (bnc#1027565).

Special Instructions and Notes:

• Please reboot the system after installing this update.

Patch Instructions:

To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
