Security update for xen

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).

Описание

A parameter verification issue was discovered in Xen through 4.9.x. The function `alloc_heap_pages` allows callers to specify the first NUMA node that should be used for allocations through the `memflags` parameter; the node is extracted using the `MEMF_get_node` macro. While the function checks to see if the special constant `NUMA_NO_NODE` is specified, it otherwise does not handle the case where `node >= MAX_NUMNODES`. This allows an out-of-bounds access to an internal array.

Описание

A domain cleanup issue was discovered in the C xenstore daemon (aka cxenstored) in Xen through 4.9.x. When shutting down a VM with a stubdomain, a race in cxenstored may cause a double-free. The xenstored daemon may crash, resulting in a DoS of any parts of the system relying on it (including domain creation / destruction, ballooning, device changes, etc.).

A grant unmapping issue was discovered in Xen through 4.9.x. When removing or replacing a grant mapping, the x86 PV specific path needs to make sure page table entries remain in sync with other accounting done. Although the identity of the page frame was validated correctly, neither the presence of the mapping nor page writability were taken into account.
