kernel: xen: Page reference counting error due to XSA-45/CVE-2013-1918 fixes
Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature page free and hypervisor crash) or possibly gain privileges via unspecified vectors.
Statement: Not vulnerable.
This issue did not affect the versions of the kernel-xen package as shipped with Red Hat Enterprise Linux 5 because we did not backport CVE-2013-1918 fix.
This issue did not affect Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2 because of missing Xen hypervisor support.

Statement: This issue did affect the versions of the kernel-xen package as shipped with Red Hat Enterprise Linux 5.
This issue did not affect Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2.
The risks associated with fixing this bug are greater than its security impact. This issue is not currently planned to be addressed in future kernel-xen updates for Red Hat Enterprise Linux 5. Using fully virtualized (HVM) guests, or PV guests with trusted kernel/administrator avoids this issue.

CVE-2013-1432 [HIGH] CVE-2013-1432 kernel: xen: Page reference counting error due to XSA-45/CVE-2013-1918 fixes
CVE-2013-1432 kernel: xen: Page reference counting error due to XSA-45/CVE-2013-1918 fixes
The XSA-45/CVE-2013-1918 patch making error handling paths preemptible broke page reference counting by not retaining a reference on pages stored for deferred cleanup. This would lead to the hypervisor prematurely attempting to free the page, generally crashing upon finding the page still in use.
Malicious or buggy PV guest kernels can mount a denial of service attack affecting the whole system. It can't be excluded that this could also be exploited to mount a privilege escalation attack.

CVE-2013-1918 kernel: xen: Several long latency operations are not preemptible
Page table manipulation operations for PV guests can take significant amounts of time, as they require all present branches to have their type (and thus contents) verified. While the most frequently used operations had been made preemptible in the past, some code paths involving potentially deep page table traversal were still trying to do their entire work in a single step.
Malicious or buggy PV guest kernels could potentially mount a denial of service attack affecting the whole system.
