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 •

https://notcve.org/view.php?id=CVE-2009-1630
The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel 2.6.29.3 and earlier, when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver. La función nfs_permission en fs/nfs/dir.c en la implementación cliente NFS en Linux kernel v2.6.29.3 y versiones anteriores, cuando atomic_open está activo, no comprueba la ejecución (también conocido como EXEC or MAY_EXEC) de permisos de bits, lo cual permite a usuarios locales evitar permisos y ejecutar ficheros, como lo demostrado por ficheros en un servidor de ficheros NFSv4. • http://article.gmane.org/gmane.linux.nfs/26592 http://bugzilla.linux-nfs.org/show_bug.cgi?id=131 http://linux-nfs.org/pipermail/nfsv4/2006-November/005313.html http://linux-nfs.org/pipermail/nfsv4/2006-November/005323.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2009-07/msg00004.html http://secunia.com/advisories/35106 http://secunia.com/advisories/35298 http://secunia.com/advisories/35394 http&# • CWE-264: Permissions, Privileges, and Access Controls •

https://notcve.org/view.php?id=CVE-2009-1527
Race condition in the ptrace_attach function in kernel/ptrace.c in the Linux kernel before 2.6.30-rc4 allows local users to gain privileges via a PTRACE_ATTACH ptrace call during an exec system call that is launching a setuid application, related to locking an incorrect cred_exec_mutex object. Condición de carrera en la función ptrace_attach en kernel/ptrace.c en el kernel de Linux anterior a 2.6.40-rc4 permite a usuarios locales conseguir privilegios a través de la llamada PTRACE_ATTACH ptrace durante una ejecución de sistema que esta lanzando una aplicacion setuid, relacionada con el incorrecto bloqueo del objeto cred_exec_mutex. • https://www.exploit-db.com/exploits/8673 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=cad81bc2529ab8c62b6fdc83a1c0c7f4a87209eb http://secunia.com/advisories/34977 http://secunia.com/advisories/35120 http://wiki.rpath.com/Advisories:rPSA-2009-0084 http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.30-rc4 http://www.openwall.com/lists/oss-security/2009/05/04/2 http://www.osvdb.org/54188 http://www.securityfocus.com/archi • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
