CVSS: 7.2EPSS: 0%CPEs: 340EXPL: 1CVE-2009-4131 – Linux Kernel 2.6.x - Ext4 'move extents' ioctl Privilege Escalation
https://notcve.org/view.php?id=CVE-2009-4131
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 •

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 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.
