https://notcve.org/view.php?id=CVE-2009-2692
The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket. El kernel de Linux versiones 2.6.0 hasta 2.6.30.4 y 2.4.4 hasta 2.4.37.4, no inicia todos los punteros de función para operaciones de socket en estructuras de proto_ops, lo que permite a los usuarios locales activar una desreferencia de puntero NULL y alcanzar privilegios mediante el uso de mmap que asigna la página cero, inserta el código arbitrario en esta página y luego invoca una operación no disponible, como es demostrado por la operación de sendpage (función sock_sendpage) en un socket PF_PPPOX. • https://www.exploit-db.com/exploits/9477 https://www.exploit-db.com/exploits/19933 https://www.exploit-db.com/exploits/9545 https://www.exploit-db.com/exploits/9598 https://www.exploit-db.com/exploits/9479 https://www.exploit-db.com/exploits/9641 https://www.exploit-db.com/exploits/9435 https://www.exploit-db.com/exploits/9436 https://github.com/jdvalentini/CVE-2009-2692 http://archives.neohapsis.com/archives/fulldisclosure/2009-08/0174.html http://blog.cr0.or • CWE-476: NULL Pointer Dereference CWE-908: Use of Uninitialized Resource •

nfsd in the Linux kernel before 2.6.28.9 does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option. nfsd en el Kernel de Linux anteriores a la v2.6.28.9 no detiene la capacidad de CAP_MKNOD antes del manejo de una petición de usuario en un hilo, lo que permite a usuarios locales crear nodos de dispositivo, como se ha demostrado en un sistema de ficheros que ha sido exportado con la opción root_squash. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=76a67ec6fb79ff3570dcb5342142c16098299911 http://lists.opensuse.org/opensuse-security-announce/2009-04/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2009-05/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00001.html http://secunia.com/advisories/34422 http://secunia.com/advisories/34432 http://sec • CWE-16: Configuration •

https://notcve.org/view.php?id=CVE-2009-0778
The icmp_send function in net/ipv4/icmp.c in the Linux kernel before 2.6.25, when configured as a router with a REJECT route, does not properly manage the Protocol Independent Destination Cache (aka DST) in some situations involving transmission of an ICMP Host Unreachable message, which allows remote attackers to cause a denial of service (connectivity outage) by sending a large series of packets to many destination IP addresses within this REJECT route, related to an "rt_cache leak." La función icmp_send en net/ipv4/icmp.c en el kernel Linux anerior a v2.6.25, cuando se configura como un router con una ruta RECHAZADA, no gestiona apropiadamente el Protocolo Independiente de Caché de Destino (alias DST) en alguna situación que involucra transmisión de un mensaje ICMP Host inalcanzable, el cual permite a los atacantes remotos causar una denegación de servicio (conectividad parada) enviando una larga serie de paquetes a muchos direcciones IP de destino con esta ruta RECHAZADA, RELATIVA a "rt_cache leak." • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7c0ecc4c4f8fd90988aab8a95297b9c0038b6160 http://openwall.com/lists/oss-security/2009/03/11/2 http://secunia.com/advisories/33758 http://secunia.com/advisories/37471 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.25 http://www.redhat.com/support/errata/RHSA-2009-0326.html http://www.securityfocus.com/archive/1/507985/100/0/threaded http://www.securityfocus.com/bid/34084 http:/&#x • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2009-0834
The audit_syscall_entry function in the Linux kernel 2.6.28.7 and earlier on the x86_64 platform does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls, a related issue to CVE-2009-0342 and CVE-2009-0343. La función audit_syscall_entry en el núcleo de Linux v2.6.28.7 y versiones anteriores en la plataforma x86_64 no maneja adecuadamente (1) un proceso de 32-bit haciendo una llamada al sistema (syscall) de 64 bit o (2) un proceso de 64-bit haciendo una llamada al sistema (syscall) de 32-bit, lo cual permite a usuarios locales evitar determinadas configuraciones de auditoría de llamadas al sistema (syscall) a través de llamadas al sistema (syscall) manipuladas, una cuestión diferente a VE-2009-0342 y CVE-2009-0343. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ccbe495caa5e604b04d5a31d7459a6f6a76a756c http://lists.opensuse.org/opensuse-security-announce/2009-05/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00001.html http://marc.info/?l=linux-kernel&m=123579056530191&w=2 http://marc.info/?l=linux-kernel&m=123579065130246&w=2 http://marc.info/?l=oss-security&m •
