CVE-2011-1583 medium priority: Ubuntu including 4 source packages (xen, xen-3.1, xen-3.2, xen-3.3), 40 status rows across 10 suites (hardy, lucid, maverick, natty, oneiric, precise, quantal, raring, saucy, upstream): DNE 26, ignored 5, not-affected 5, needs-triage 3, released 1.
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.
