The irda_bind function in net/irda/af_irda.c in the Linux kernel before 2.6.36-rc3-next-20100901 does not properly handle failure of the irda_open_tsap function, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact via multiple unsuccessful calls to bind on an AF_IRDA (aka PF_IRDA) socket. La función irda_bind en net/irda/af_irda.c en el kernel de Linux anterior v2.6.36-rc3-next-20100901 no maneja adecuadamente los fallos de la función irda_open_tsap, lo que permite a usuarios locales causar una denegación de servicio(desreferencia a puntero NULL y panico) y probablemente otros impactos no especificados a través de múltiples llamadas no exitosas en el socket AF_IRDA (conocido como PF_IRDA). • http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.git%3Ba=commit%3Bh=628e300cccaa628d8fb92aa28cb7530a3d5f2257 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2010-11/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2011-02/msg00000.html http://marc.info/?l=oss-security&m=128331787923285&w=2 http://secunia.com/advisories/4 • CWE-476: NULL Pointer Dereference •

Race condition in the tty_fasync function in drivers/char/tty_io.c in the Linux kernel before 2.6.32.6 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via unknown vectors, related to the put_tty_queue and __f_setown functions. NOTE: the vulnerability was addressed in a different way in 2.6.32.9. Condición de carrera en la función tty_fasync en drivers/char/tty_io.c en el kernel de Linux v2.6.32.6, permite a usuarios locales provocar una denegación de servicio (deferencia puntero nulo o caída del sistema) o posiblemente tener otro impacto no especificado a través de vectores desconocidos, relacionado con las funciones put_tty_queue y __f_setown. NOTA: la vulnera fue dirigida de un modo distinto en v2.6.32.9. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=703625118069f9f8960d356676662d3db5a9d116 http://www.debian.org/security/2010/dsa-2094 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.32.6 http://www.openwall.com/lists/oss-security/2010/06/15/2 http://www.openwall.com/lists/oss-security/2010/06/15/3 http://www.openwall.com/lists/oss-security/2010/06/15/4 http://www.openwall.com/lists/oss-security/2010/06/15/5 http • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-476: NULL Pointer Dereference •

fs/cifs/cifssmb.c in the CIFS implementation in the Linux kernel before 2.6.34-rc4 allows remote attackers to cause a denial of service (panic) via an SMB response packet with an invalid CountHigh value, as demonstrated by a response from an OS/2 server, related to the CIFSSMBWrite and CIFSSMBWrite2 functions. Las funciones CIFSSMBWrite y CIFSSMBWrite2 de fs/cifs/cifssmb.c en la aplicación CIFS del kernel de Linux antes de v2.6.34-rc4 permiten a atacantes remotos provocar una denegación de servicio (mediante un panic del kernel) a través de un paquete de respuesta SMB con un valor 'CountHigh' no válido, como lo demuestra una respuesta de un servidor OS/2. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=6513a81e9325d712f1bfb9a1d7b750134e49ff18 http://lists.opensuse.org/opensuse-security-announce/2010-12/msg00004.html http://secunia.com/advisories/43315 http://securitytracker.com/id?1024285 http://www.debian.org/security/2010/dsa-2094 http://www.kernel.org/pub/linux/kernel/v2.6/testing/v2.6.34/ChangeLog-2.6.34-rc4 http://www.mandriva.com/security/advisories?name=MDVSA-2010:198 http://www.mandriva.com&# • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •

Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel before 2.6.34-rc6 allow remote attackers to cause a denial of service (panic) or possibly execute arbitrary code via a crafted NFSv4 compound WRITE request, related to the read_buf and nfsd4_decode_compound functions. Múltiples desbordamientos de búfer en fs/nfsd/nfs4xdr.c en la aplicación XDR en el servidor NFS del kernel de Linux antes de v2.6.34-rc6 permiten a atacantes remotos provocar una denegación de servicio (mediante un 'panic' del kernel) o posiblemente ejecutar código arbitrario a través de una petición WRITE de NFSv4 debidamente modificada. El problema esta relacionado con las funciones read_buf y nfsd4_decode_compound. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=2bc3c1179c781b359d4f2f3439cb3df72afc17fc http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00004.html http://secunia.com/advisories/43315 http://securitytracker.com/id?1024286 http://www.debian.org/security/2010/dsa-2094 http://www.kernel.org/pub/linux/kernel/v2.6/testing/v2.6.34/ChangeLog-2.6.34-rc6 http://www.mandriva.com/security/advisories?name=MDVSA-2010:198 http://www.mandriva.com&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel before 2.6.35 uses an incorrect size value in calculations associated with sentinel directory entries, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c. La función gfs2_dirent_find_space en fs/gfs2/dir.c en el kernel de Linux anterior a v 2.6.35, usa un valor de tamaño incorrecto en los cálculos asociados con las entradas del directorio "sentinel", lo que permite a usuarios locales provocar una denegación de servicio (deferencia a puntero nullo y kernel panic) y posiblemente otro impacto no especificados mediante el renombrado de un archivo en un sistema de fichero GFS2, relacionado con la función gfs2_rename en fs/gfs2/ops_inode.c. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=728a756b8fcd22d80e2dbba8117a8a3aafd3f203 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2010-11/msg00000.html http://secunia.com/advisories/46397 http://securitytracker.com/id?1024386 http://support.avaya.com/css/P8/documents/100113326 http://www.debian.org/security/2010/dsa-2094 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLo • CWE-476: NULL Pointer Dereference •
