https://notcve.org/view.php?id=CVE-2009-1758
The hypervisor_callback function in Xen, possibly before 3.4.0, as applied to the Linux kernel 2.6.30-rc4, 2.6.18, and probably other versions allows guest user applications to cause a denial of service (kernel oops) of the guest OS by triggering a segmentation fault in "certain address ranges." La función hypervisor_callback en Xen, posiblemente anteriores a v3.4.0, como la que se aplica al kernel de linux v2.6.30-rc4, 2.6.18 y posiblemente otroas versiones permiten a aplicaciones del usuario guess provocar una denegación de servicio (kernel opps) en el sistema invitado mediante cuando se provoca un fallo de segmentación en "determinados rangos de direcciones". • http://lists.xensource.com/archives/html/xen-devel/2009-05/msg00561.html http://secunia.com/advisories/35093 http://secunia.com/advisories/35298 http://www.debian.org/security/2009/dsa-1809 http://www.openwall.com/lists/oss-security/2009/05/14/2 http://www.securityfocus.com/bid/34957 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A10313 https://access.redhat.com/security/cve/CVE-2009-1758 https://bugzilla.redhat.com/show_bug.cgi?id= • CWE-399: Resource Management Errors •
