CVSS: 7.1EPSS: 1%CPEs: 358EXPL: 1CVE-2009-0778 – kernel: rt_cache leak leads to lack of network connectivity
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 •

The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel before 2.6.28.5, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program. La función shm_get_stat en ipc/shm.c del subsistema shm en el Kernell de Linux anteriores a v2.6.28.5, cuando CONFIG_SHMEM está desactivado, interpreta de forma errónea el tipo de datos en un inode, lo que permite a usuarios locales provocar una denegación de servicios (cuelgue del sistema) a través de una llamada shmctl SHM_INFO, como se ha demostrado ejecutando el programa ipcs. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a68e61e8ff2d46327a37b69056998b47745db6fa http://kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.28.5 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=git-commits-head&m=123387479500599&w=2 http://marc.info/?l=l • CWE-20: Improper Input Validation •

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 •
