CVE-2010-4525 – kvm: x86: zero kvm_vcpu_events->interrupt.pad infoleak
https://notcve.org/view.php?id=CVE-2010-4525
Linux kernel 2.6.33 and 2.6.34.y does not initialize the kvm_vcpu_events->interrupt.pad structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via unspecified vectors. El kernel de Linux v2.6.33 y v2.6.34.y no inicializa la estructura miembro kvm_vcpu_events->interrupt.pad, lo que permite a usuarios locales obtener información sensible de la pila del núcleo de la memoria a través de vectores no especificados. • http://osvdb.org/70377 http://secunia.com/advisories/42890 http://www.openwall.com/lists/oss-security/2011/01/05/1 http://www.openwall.com/lists/oss-security/2011/01/05/9 http://www.openwall.com/lists/oss-security/2011/01/06/3 http://www.redhat.com/support/errata/RHSA-2011-0007.html http://www.redhat.com/support/errata/RHSA-2011-0028.html http://www.securityfocus.com/bid/45676 http://www.vupen.com/english/advisories/2011/0123 https://bugzilla.redhat • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2010-4247 – xen: request-processing loop is unbounded in blkback
https://notcve.org/view.php?id=CVE-2010-4247
The do_block_io_op function in (1) drivers/xen/blkback/blkback.c and (2) drivers/xen/blktap/blktap.c in Xen before 3.4.0 for the Linux kernel 2.6.18, and possibly other versions, allows guest OS users to cause a denial of service (infinite loop and CPU consumption) via a large production request index to the blkback or blktap back-end drivers. NOTE: some of these details are obtained from third party information. La función do_block_io_op en (1) ldrivers/xen/blkback/blkback.c and (2) drivers/xen/blktap/blktap.c en Xen anterior a v3.4.0 para el kernel Linux v2.6.18, y posiblemente otras versiones, permite a los usuarios invitados del sistema operativo causar una denegación de servicio (bucle infinito y el consumo de CPU) a través de un gran índice de producción de peticiones a los controladores blkback o blktap back-end.
