CVE-2013-4370 is a vulnerability of currently unknown severity. The ocaml binding for the xc_vcpu_getaffinity function in Xen 4.2.x and 4.3.x frees certain memory that may still be intended for use, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors that trigger a (1) use-after-free or (2) double free.. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
