https://notcve.org/view.php?id=CVE-2012-1583

Double free vulnerability in the xfrm6_tunnel_rcv function in net/ipv6/xfrm6_tunnel.c in the Linux kernel before 2.6.22, when the xfrm6_tunnel module is enabled, allows remote attackers to cause a denial of service (panic) via crafted IPv6 packets. Vulnerabilidad de liberación doble en la función xfrm6_tunnel_rcv en net/ipv6/xfrm6_tunnel.c en el kernel de Linux anterior a v2.6.22, cuando el módulo xfrm6_tunnel está activada, permite a atacantes remotos causar una denegación de servicio (pánico) a través de hechos a mano los paquetes IPv6. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.22 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=d0772b70faaf8e9f2013b6c4273d94d5eac8047a http://marc.info/?l=bugtraq&m=133951357207000&w=2 http://rhn.redhat.com/errata/RHSA-2012-0488.html http://secunia.com/advisories/48881 http://www.securityfocus.com/bid/53139 http://www.securitytracker.com/id?1026930 https://bugzilla.redhat.com/show_bug.cgi?id=752304 https://github.com/torval • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-399: Resource Management Errors •

CVE-2012-1097 – kernel: regset: Prevent null pointer reference on readonly regsets

https://notcve.org/view.php?id=CVE-2012-1097

The regset (aka register set) feature in the Linux kernel before 3.2.10 does not properly handle the absence of .get and .set methods, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a (1) PTRACE_GETREGSET or (2) PTRACE_SETREGSET ptrace call. El funcionalidad regset (también conocido como conjunto de registros) en el kernel de Linux antes de v3.2.10 no controla correctamente la ausencia de métodos ."set" y ".get", lo que permite a usuarios locales causar una denegación de servicio (desreferencia de puntero nulo) o, posiblemente, tener un impacto no especificado a través de (1) un PTRACE_GETREGSET o (2) una llamada ptrace PTRACE_SETREGSET. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c8e252586f8d5de906385d8cf6385fee289a825e http://lists.opensuse.org/opensuse-security-announce/2012-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2012-05/msg00013.html http://rhn.redhat.com/errata/RHSA-2012-0481.html http://rhn.redhat.com/errata/RHSA-2012-0531.html http://secunia.com/advisories/48842 http://secunia.com/advisories/48898 http://secunia.com/advisories/48964 http://www.k • CWE-476: NULL Pointer Dereference •

CVE-2012-1090 – kernel: cifs: dentry refcount leak when opening a FIFO on lookup leads to panic on unmount

https://notcve.org/view.php?id=CVE-2012-1090

The cifs_lookup function in fs/cifs/dir.c in the Linux kernel before 3.2.10 allows local users to cause a denial of service (OOPS) via attempted access to a special file, as demonstrated by a FIFO. La función cifs_lookup en fs/cifs/dir.c en el núcleo de Linux anteriores a v3.2.10 permite a usuarios locales causar una denegación de servicio (OOPS) a través de intentos de acceso a un archivo especial, como lo demuestra un FIFO. • http://lists.opensuse.org/opensuse-security-announce/2012-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2012-05/msg00013.html http://rhn.redhat.com/errata/RHSA-2012-0481.html http://rhn.redhat.com/errata/RHSA-2012-0531.html http://secunia.com/advisories/48842 http://secunia.com/advisories/48964 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.10 http://www.openwall.com/lists/oss-security/2012/02/28/4 https://bugzilla.redhat.com/show • CWE-20: Improper Input Validation •

CVE-2012-1146

https://notcve.org/view.php?id=CVE-2012-1146

The mem_cgroup_usage_unregister_event function in mm/memcontrol.c in the Linux kernel before 3.2.10 does not properly handle multiple events that are attached to the same eventfd, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by registering memory threshold events. La función mem_cgroup_usage_unregister_event en mm/memcontrol.c en el núcleo de Linux anteriores a v3.2.10 no maneja apropiadamente múltiples eventos que son asociados al mismo eventfd, lo cual permite a usuarios locales causar una denegación de servicio (puntero nulo sin referencia y caída del sistema) o posiblemente tener un impacto no especificado por el registro de eventos en el límite de la memoria. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=371528caec553785c37f73fa3926ea0de84f986f http://lists.fedoraproject.org/pipermail/package-announce/2012-March/075781.html http://lists.opensuse.org/opensuse-security-announce/2012-04/msg00021.html http://secunia.com/advisories/48898 http://secunia.com/advisories/48964 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.10 http://www.openwall.com/lists/oss-security/2012/03/07/3 https://bugzilla.redhat • CWE-476: NULL Pointer Dereference •

CVE-2011-4621 – kernel: tight loop and no preemption can cause system stall

https://notcve.org/view.php?id=CVE-2011-4621

The Linux kernel before 2.6.37 does not properly implement a certain clock-update optimization, which allows local users to cause a denial of service (system hang) via an application that executes code in a loop. El kernel de Linux antes de v2.6.37 no aplica la optimización de una actualización de reloj, lo que permite a usuarios locales provocar una denegación de servicio (bloqueo del sistema) a través de una aplicación que ejecuta código en un bucle. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.37 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=f26f9aff6aaf67e9a430d16c266f91b13a5bff64 http://www.openwall.com/lists/oss-security/2011/12/21/6 https://bugzilla.redhat.com/show_bug.cgi?id=769711 https://github.com/torvalds/linux/commit/f26f9aff6aaf67e9a430d16c266f91b13a5bff64 https://access.redhat.com/security/cve/CVE-2011-4621 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
