DEBIAN-CVE-2012-3432

The handlemmio function in arch/x86/hvm/io.c in the MMIO operations emulator for Xen 3.3 and 4.x, when running an HVM guest, does not properly reset certain state information between emulation cycles, which allows local guest OS users to cause a denial of service guest OS crash via unspecified...

Memory mapping failure DoS vulnerability

ISSUE DESCRIPTION When setp2mentry fails, Xen's internal data structures the p2m and m2p tables can get out of sync. This failure can be triggered by unusual guest behaviour exhausting the memory reserved for the p2m table. If it happens, subsequent guest-invoked memory operations can cause Xen t...

Scientific Linux Security Update : kvm on SL5.x x86_64

It was found that QEMU-KVM on the host did not validate all pointers provided from a guest system's QXL graphics card driver. A privileged guest user could use this flaw to cause the host to dereference an invalid pointer, causing the guest to crash denial of service or, possibly, resulting in th...
