Unspecified vulnerability in the EXT4_IOC_MOVE_EXT (aka move extents) ioctl implementation in the ext4 filesystem in the Linux kernel 2.6.32-git6 and earlier allows local users to cause a denial of service (filesystem corruption) via unknown vectors, a different vulnerability than CVE-2009-4131. Vulnerabilidad sin especificar en la implementación EXT4_IOC_MOVE_EXT (también conocido como "move extents") ioctl en el sistema de ficheros ext4 en el kernel de Linux v2.6.32-git6 y anteriores permite a usuarios locales producir una denegación de servicio (corrupción del sistema de ficheros) a través de vectores desconocidos, una vulnerabilidad diferente que CVE-2009-4131. • http://grsecurity.org/test/grsecurity-2.1.14-2.6.32-200912112157.patch http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00000.html http://secunia.com/advisories/38017 http://twitter.com/fotisl/statuses/6568947714 http://twitter.com/spendergrsec/statuses/6551797457 http://twitter.com/spendergrsec/statuses/6567167692 http://twitter.com/spendergrsec/statuses/6569596339 http://twitter.com/spendergrsec/statuses/6572069107 http://twitter.com/spendergrsec/statuses/6583954567 http://twitter.com& •

https://notcve.org/view.php?id=CVE-2009-4307
The ext4_fill_flex_info function in fs/ext4/super.c in the Linux kernel before 2.6.32-git6 allows user-assisted remote attackers to cause a denial of service (divide-by-zero error and panic) via a malformed ext4 filesystem containing a super block with a large FLEX_BG group size (aka s_log_groups_per_flex value). La funcion ext4_fill_flex_info en fs/ext4/super.c en el kernel de Linux anteriores a v2.6.32-git6 permite a atacantes remotos asistidos por el usuario producir una denegación de servicio (error de división por cero y panic) a través de un sistema de ficheros ext4 malformado que contenga un super bloque con un valor de tamaño de grupo FLEX_BG grande (también conocido como valor s_log_groups_per_flex). • http://bugzilla.kernel.org/show_bug.cgi?id=14287 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=503358ae01b70ce6909d19dd01287093f6b6271c http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00005.html http://lkml.org/lkml/2009/12/9/255 http://secunia.com/advisories/37658 http://secunia.com/advisories/38017 http://secunia.com/advisories/38276 http://www.kernel.org&#x • CWE-189: Numeric Errors •

The ext4_decode_error function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference), and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal. La funcion ext4_decode_error en fs/ext4/super.c en el sistema de ficheros ext4 en el kernel de Linux anteriores a v2.6.32 permite a atacantes remotos asistidos por el usuario producir una denegación de servicio (desreferencia a punteru NULL), y posiblemente tienes mas impacto sin especificar, a través de de un sistema de ficheros solo de lectura que carece de journal. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=78f1ddbb498283c2445c11b0dfa666424c301803 http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00005.html http://secunia.com/advisories/37658 http://secunia.com/advisories/38017 http://secunia.com/advisories/38276 http://secunia.com/advisories/43315 http://www • CWE-399: Resource Management Errors CWE-476: NULL Pointer Dereference •

The EXT4_IOC_MOVE_EXT (aka move extents) ioctl implementation in the ext4 filesystem in the Linux kernel before 2.6.32-git6 allows local users to overwrite arbitrary files via a crafted request, related to insufficient checks for file permissions. La implementación ioctl EXT4_IOC_MOVE_EXT (tambien conocido como move extents) en el sistema de ficheros ext4 en el kernel de Linux en versiones anteriores a v2.6.32-git6 permite a usuarios locales sobrescribir ficheros arbitrariamente a través de peticiones manipuladas, relacionado con los controles insuficientes para permisos de ficheros. • https://www.exploit-db.com/exploits/33395 http://git.kernel.org/?p=linux/kernel/git/tytso/ext4.git%3Ba=commit%3Bh=4a58579b9e4e2a35d57e6c9c8483e52f6f1b7fd6 http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00000.html http://lkml.org/lkml/2009/12/9/255 http://secunia.com/advisories/37658 http://secunia.com/advisories/37686 http://secunia.com/advisories/38017 http://www.kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.32-git6.log http://www.mandriva.com/s • CWE-264: Permissions, Privileges, and Access Controls •

The ip_frag_reasm function in net/ipv4/ip_fragment.c in the Linux kernel 2.6.32-rc8, and 2.6.29 and later versions before 2.6.32, calls IP_INC_STATS_BH with an incorrect argument, which allows remote attackers to cause a denial of service (NULL pointer dereference and hang) via long IP packets, possibly related to the ip_defrag function. La función ip_frag_reasm en el archivo net/ipv4/ip_fragment.c en el kernel de Linux versiones 2.6.32-rc8, y 2.6.29 y versiones posteriores anteriores a 2.6.32, llama a IP_INC_STATS_BH con un argumento incorrecto, que permite a atacantes remotos causar una denegación de servicio (suspensión y desreferencia de puntero NULL) por medio de paquetes IP largos, posiblemente relacionados con la función ip_defrag. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=bbf31bf18d34caa87dd01f08bf713635593697f2 http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00000.html http://secunia.com/advisories/37624 http://secunia.com/advisories/38017 http://twitter.com/spendergrsec/statuses/6339560349 http://wiki.rpath.com/Advisories:rPSA-2009-0161 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.32 http://www.mandriva.com/security/advisories?name=MDVSA-2009:329& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
