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.

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.
Package: kernel-xen (Red Hat Enterprise Linux 5) - Not affected

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.
