SUSE SLES11 Security Update : xen (SUSE-SU-2017:2611-1)

High Nessus Plugin ID 103636


The remote SUSE host is missing one or more security updates.


This update for xen fixes several issues. These security issues were fixed :

- CVE-2017-14316: Missing bound check in function `alloc_heap_pages` for an internal array allowed attackers using crafted hypercalls to execute arbitrary code within Xen (XSA-231, bsc#1056278)

- CVE-2017-14317: A race in cxenstored may have cause a double-free allowind for DoS of the xenstored daemon (XSA-233, bsc#1056281).

- CVE-2017-14319: An error while handling grant mappings allowed malicious or buggy x86 PV guest to escalate its privileges or crash the hypervisor (XSA-234, bsc#1056282).

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.
