https://notcve.org/view.php?id=CVE-2009-4020
Stack-based buffer overflow in the hfs subsystem in the Linux kernel 2.6.32 allows remote attackers to have an unspecified impact via a crafted Hierarchical File System (HFS) filesystem, related to the hfs_readdir function in fs/hfs/dir.c. Desbordamiento de búfer basado en pila en el subsistema hfs de el kernel Linux v2.6.32 permite a atacantes remotos tener un impacto no especificado mediante un sistema de ficheros Hierarchical File System (HFS) modificado, relacionado con la función hfs_readdir en fs/hfs/dir.c. • http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-03/msg00007.html http://marc.info/?l=linux-mm-commits&m=125987755823047&w=2 http://secunia.com/advisories/38276 http://secunia.com/advisories/39742 http://support.avaya.com/css/P8/documents/100073666 http://userweb.kernel.org/~akpm/mmotm/broken-out/hfs-fix-a-potential-buffer-overflow.patch http://www.debian.org/security/2010/dsa-2005 http://www • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2009-4027 – kernel: mac80211: fix spurious delBA handling
https://notcve.org/view.php?id=CVE-2009-4027
Race condition in the mac80211 subsystem in the Linux kernel before 2.6.32-rc8-next-20091201 allows remote attackers to cause a denial of service (system crash) via a Delete Block ACK (aka DELBA) packet that triggers a certain state change in the absence of an aggregation session. Condición de carrera en el subsistema mac80211 en el kernel de Linux anteriores a 2.6.32-rc8-next-20091201 permite a atacantes remotos producir una denegación de servicio (caída de sistema) a través de un paquete de bloque de borrado ACK (también conocido como DELBA) que inicia un cambio de estado en la ausencia de una sesión de agregación. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=827d42c9ac91ddd728e4f4a31fefb906ef2ceff7 http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00000.html http://secunia.com/advisories/38017 http://secunia.com/advisories/38492 http://www.debian.org/security/2010/dsa-1996 http://www.kernel.org/pub/linux/kernel/v2.6/next/patch-v2.6.32-rc8-next-20091201.gz http://www.redhat.com/support/errata/RHSA-2010-0380.html http://www.securityfocus.com • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-617: Reachable Assertion •

The mac80211 subsystem in the Linux kernel before 2.6.32-rc8-next-20091201 allows remote attackers to cause a denial of service (panic) via a crafted Delete Block ACK (aka DELBA) packet, related to an erroneous "code shuffling patch." El subsistema mac80211 en el kernel de linux anterior a 2.6.32-rc8-next-20091201, permite a atacantes remotos provocar una denegación de servicio (panic) a través de un un Delete Block ACK (también conocido como DELBA) manipulado.

CVE-2009-4031 – kernel: KVM: x86 emulator: limit instructions to 15 bytes
https://notcve.org/view.php?id=CVE-2009-4031
The do_insn_fetch function in arch/x86/kvm/emulate.c in the x86 emulator in the KVM subsystem in the Linux kernel before 2.6.32-rc8-next-20091125 tries to interpret instructions that contain too many bytes to be valid, which allows guest OS users to cause a denial of service (increased scheduling latency) on the host OS via unspecified manipulations related to SMP support. La función do_insn_fetch en arch/x86/kvm/emulate.c en el emulador x86 KVM en el subsystem del kernel de Linux anterior a 2.6.32-rc8-next-20091125 intenta interpretar instrucciones que contienen demasiados bytes para ser válidas, lo que permite a un usuario invitado del sistema operativo provocar una denegación de servicio (incremento de la latencia de la planificación) en el sistema operativo anfitrión a través de manipulaciones no especificadas relacionadas con el soporte SMP. • http://git.kernel.org/?p=linux/kernel/git/avi/kvm.git%3Ba=commit%3Bh=e42d9b8141d1f54ff72ad3850bb110c95a5f3b88 http://lists.opensuse.org/opensuse-security-announce/2010-03/msg00006.html http://secunia.com/advisories/37720 http://www.kernel.org/pub/linux/kernel/v2.6/next/patch-v2.6.32-rc8-next-20091125.gz http://www.openwall.com/lists/oss-security/2009/11/25/1 http://www.openwall.com/lists/oss-security/2009/11/25/3 http://www.securityfocus.com/bid/37130 https://bugzilla • CWE-20: Improper Input Validation •
CVE-2009-4021 – kernel: fuse: prevent fuse_put_request on invalid pointer
https://notcve.org/view.php?id=CVE-2009-4021
The fuse_direct_io function in fs/fuse/file.c in the fuse subsystem in the Linux kernel before 2.6.32-rc7 might allow attackers to cause a denial of service (invalid pointer dereference and OOPS) via vectors possibly related to a memory-consumption attack. La funcion fuse_direct_io en fs/fuse/file.c en el subsistema fuse en el kernel de Linux en versiones anteriores a v2.6.32-rc7 podría permitir a atacantes producir una denegación de servicio (desreferencia a puntero no valido y OOPS) a través de vectores que posiblemente estén relacionados con un ataque de agotamiento de memoria. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=f60311d5f7670d9539b424e4ed8b5c0872fc9e83 http://lists.opensuse.org/opensuse-security-announce/2009-12/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2009-12/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00005.html http://secunia.com/advisories/37909 http://secunia.com/advisories/38017 http://support • CWE-399: Resource Management Errors •
