An update that solves one vulnerability and has one security fix can now be installed.
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)
Special Instructions and Notes:
