"The SUSE Linux Enterprise 12 SP2 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 update package also includes non-security fixes. See advisory for
details.
