https://notcve.org/view.php?id=CVE-2011-2525
The qdisc_notify function in net/sched/sch_api.c in the Linux kernel before 2.6.35 does not prevent tc_fill_qdisc function calls referencing builtin (aka CQ_F_BUILTIN) Qdisc structures, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a crafted call. La función qdisc_notify de net/sched/sch_api.c del kernel de Linux en versiones anteriores a la 2.6.35 no previene que la función tc_fill_qdisc haga referencia a estructuras Qdisc (CQ_F_BUILTIN) pre-construídas, lo que permite a usuarios locales provocar una denegación de servicio (resolución de puntero NULL y OOPS) o posiblemente tener otros impactos sin especificar a través de una llamada modificada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=53b0f08042f04813cd1a7473dacd3edfacb28eb3 http://kerneltrap.org/mailarchive/linux-netdev/2010/5/21/6277805 http://mirror.anl.gov/pub/linux/kernel/v2.6/ChangeLog-2.6.35 http://openwall.com/lists/oss-security/2011/07/12/1 http://rhn.redhat.com/errata/RHSA-2011-1065.html http://rhn.redhat.com/errata/RHSA-2011-1163.html https://bugzilla.redhat.com/show_bug.cgi?id=720552 https://access.redhat. • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2010-4251
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests. La implementación del socket en net/core/sock.c en el kernel de Linux anterior a v2.6.34 no maneja correctamente un retraso de los paquetes recibidos, que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) mediante el envío de una gran cantidad de la red tráfico, como lo demuestran las pruebas netperf UDP. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=8eae939f1400326b06d0c9afe53d2a484a326871 http://kerneltrap.org/mailarchive/linux-netdev/2010/3/3/6271093/thread http://secunia.com/advisories/46397 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.34 http://www.securityfocus.com/archive/1/520102/100/0/threaded http://www.securityfocus.com/bid/46637 http://www.vmware.com/security/advisories/VMSA-2011-0012.html https://bugzilla.redhat.com/sh • CWE-400: Uncontrolled Resource Consumption •

The socket implementation in net/core/sock.c in the Linux kernel before 2.6.35 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service by sending a large amount of network traffic, related to the sk_add_backlog function and the sk_rmem_alloc socket field. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-4251. La implementación del socket en net/core/sock.c en el kernel de Linux anteriores a v2.6.35 no maneja correctamente un retraso de los paquetes recibidos, lo que permite a atacantes remotos provocar una denegación de servicio mediante el envío de una gran cantidad de tráfico de la red, relacionados con la función sk_add_backlog y el campo de toma de sk_rmem_alloc.

https://notcve.org/view.php?id=CVE-2011-1011
The seunshare_mount function in sandbox/seunshare.c in seunshare in certain Red Hat packages of policycoreutils 2.0.83 and earlier in Red Hat Enterprise Linux (RHEL) 6 and earlier, and Fedora 14 and earlier, mounts a new directory on top of /tmp without assigning root ownership and the sticky bit to this new directory, which allows local users to replace or delete arbitrary /tmp files, and consequently cause a denial of service or possibly gain privileges, by running a setuid application that relies on /tmp, as demonstrated by the ksu application. La función seunshare_mount en sandbox/seunshare.c en seunshare en ciertos paquetes de Red Hat de policycoreutils v2.0.83 y anteriores de Red Hat Enterprise Linux (RHEL) v6 y anteriores, y Fedora v14 y anteriores, monta un nuevo directorio en la parte superior de /tmp sin asignar la pertenencia de root y el bit sticky a este nuevo directorio, lo que permite a usuarios locales reemplazar o eliminar de archivos /tmp de su elección, y por lo tanto provocar una denegación de servicio o ganar privilegios en su caso, mediante la ejecución de una aplicación setuid que se basa en /tmp, como demostrado por la aplicación de KSU. • http://archives.neohapsis.com/archives/fulldisclosure/2011-02/0585.html http://lists.fedoraproject.org/pipermail/package-announce/2011-March/056227.html http://openwall.com/lists/oss-security/2011/02/23/1 http://openwall.com/lists/oss-security/2011/02/23/2 http://pkgs.fedoraproject.org/gitweb/?p=policycoreutils.git%3Ba=blob%3Bf=policycoreutils-rhat.patch%3Bh=d4db5bc06027de23d12a4b3f18fa6f9b1517df27%3Bhb=HEAD#l2197 http://secunia.com/advisories/43415 http://secunia.com/advisories/43844 http://secunia&# • CWE-264: Permissions, Privileges, and Access Controls •
