The PyGrub boot loader in Xen unstable before changeset 25589:60f09d1ab1fe, 4.2.x, and 4.1.x allows local para-virtualized guest users to cause a denial of service memory consumption via a large 1 bzip2 or 2 lzma compressed kernel image...

SUSE CVE-2012-2934

Xen 4.0, and 4.1, when running a 64-bit PV guest on "older" AMD CPUs, does not properly protect against a certain AMD processor bug, which allows local guest OS users to cause a denial of service host hang via sequential execution of instructions across a non-canonical boundary, a different...

SUSE CVE-2012-3433

Xen 4.0 and 4.1 allows local HVM guest OS kernels to cause a denial of service domain 0 VCPU hang and kernel panic by modifying the physical address space in a way that triggers excessive shared page search time during the p2m teardown...

SUSE CVE-2012-3516

The GNTTABOPswapgrantref sub-operation in the grant table hypercall in Xen 4.2 and Citrix XenServer 6.0.2 allows local guest kernels or administrators to cause a denial of service host crash and possibly gain privileges via a crafted grant reference that triggers a write to an arbitrary hyperviso...

SUSE CVE-2012-4537

Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the setp2mentry function fails, which allows local HVM guest OS administrators to cause a denial of service memory consumption and assertion failure, aka "Memory mapping failure DoS...
