openSUSE Security Update : xen (openSUSE-2017-1071)

High Nessus Plugin ID 103291


The remote openSUSE host is missing a security update.


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-2017-14318: The function __gnttab_cache_flush missed a check for grant tables, allowing a malicious guest to crash the host or for x86 PV guests to potentially escalate privileges (XSA-232, bsc#1056280)

- 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).

These non-security issues were fixed :

- bsc#1057358: Fixed boot into SUSE Linux Enterprise 12.3 with secure boot

- bsc#1055695: Fixed restoring updates for HVM guests for ballooned domUs
