CVE-2011-1583

Multiple integer overflows in tools/libxc/xc_dom_bzimageloader.c in Xen
3.2, 3.3, 4.0, and 4.1 allow local users to cause a denial of service and
possibly execute arbitrary code via a crafted paravirtualised guest kernel
image that triggers (1) a buffer overflow during a decompression loop or
(2) an out-of-bounds read in the loader involving unspecified length
fields.
