CVSS: 2.7EPSS: 0%CPEs: 24EXPL: 0CVE-2014-4021 – xen: Hypervisor heap contents leaked to guests (xsa-100)
https://notcve.org/view.php?id=CVE-2014-4021
Xen 3.2.x through 4.4.x does not properly clean memory pages recovered from guests, which allows local guest OS users to obtain sensitive information via unspecified vectors. Xen 3.2.x hasta 4.4.x no limpia debidamente las páginas de memoria recuperadas de invitados, lo que permite a usuarios locales del sistema operativo invitado obtener información sensible a través de vectores no especificados. It was found that the Xen hypervisor implementation did not properly clean memory pages previously allocated by the hypervisor. A privileged guest user could potentially use this flaw to read data relating to other guests or the hypervisor itself. • http://linux.oracle.com/errata/ELSA-2014-0926-1.html http://linux.oracle.com/errata/ELSA-2014-0926.html http://lists.fedoraproject.org/pipermail/package-announce/2014-July/135068.html http://lists.fedoraproject.org/pipermail/package-announce/2014-July/135071.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00003.html http://secunia.com/advisories/59208 http://secunia.com/advisories/60027 http:// • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-244: Improper Clearing of Heap Memory Before Release ('Heap Inspection') •
