SUSE Security Update: Security update for the Linux Kernel ______________________________________________________________________________ Announcement ID: SUSE-SU-2017:1618-1 Rating: critical References: #1039348 #1042292 Cross-References: CVE-2017-1000364 Affected Products: SUSE Linux Enterprise Server for SAP 12 SUSE Linux Enterprise Server 12-LTSS SUSE Linux Enterprise Module for Public Cloud 12 ______________________________________________________________________________ An update that solves one vulnerability and has one errata is now available. Description: The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2017-1000364: The default stack guard page was too small and could be "jumped over" by userland programs using more than one page of stack in functions and so lead to memory corruption. This update extends the stack guard page to 1 MB (for 4k pages) and 16 MB (for 64k pages) to reduce this attack vector. This is not a kernel bugfix, but a hardening measure against this kind of userland attack.(bsc#1039348) The following non-security bugs were fixed: netfilter: A use-after-free was fixed that could cause a kernel panic on a system shutdown. (bsc#1042292) Patch Instructions: To install this SUSE Security Update use YaST online_update.
