New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionThe SUSE Linux Enterprise 12 SP1 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.
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
