CVE-2011-1583
Last modified
CVE-2011-1583 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.70% chance of exploitation in the next 30 days.
