CVE-2010-2066 – kernel: ext4: Make sure the MOVE_EXT ioctl can't overwrite append-only files
https://notcve.org/view.php?id=CVE-2010-2066
The mext_check_arguments function in fs/ext4/move_extent.c in the Linux kernel before 2.6.35 allows local users to overwrite an append-only file via a MOVE_EXT ioctl call that specifies this file as a donor. La función mext_check_arguments en fs/ext4/move_extent.c en el kernel de Linux anterior a v2.6.35, permite a usuarios locales sobrescribir una archivo de solo-añadir (append-only) a través de una llamada MOVE_EXT ioctl que especifica este archivo como un donante. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1f5a81e41f8b1a782c68d3843e9ec1bfaadf7d72 http://lists.opensuse.org/opensuse-security-announce/2010-08/msg00000.html http://secunia.com/advisories/43315 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.35 http://www.openwall.com/lists/oss-security/2010/06/07/1 http://www.openwall.com/lists/oss-security/2010/06/09/1 http://www.redhat.com/support/errata/RHSA-2010-0610.html http://w •
CVE-2010-2955 – kernel: wireless: fix 64K kernel heap content leak via ioctl
https://notcve.org/view.php?id=CVE-2010-2955
The cfg80211_wext_giwessid function in net/wireless/wext-compat.c in the Linux kernel before 2.6.36-rc3-next-20100831 does not properly initialize certain structure members, which allows local users to leverage an off-by-one error in the ioctl_standard_iw_point function in net/wireless/wext-core.c, and obtain potentially sensitive information from kernel heap memory, via vectors involving an SIOCGIWESSID ioctl call that specifies a large buffer size. La función cfg80211_wext_giwessid en net/wireless/wext-compat.c en el kernel de Linux anterior a v2.6.36-rc3-next-20100831 no inicializa adecuadamente determinadas estructuras de miembros, lo que permite a usuarios locales aprovechar un error off-by-one en la función net/wireless/wext-core.c y obtener información potencialmente sensible desde la memoria dinámica (heap) del kernel, a través de vectores que involucran una llamada SIOCGIWESSID ioctl que especifica un gran tamaño de búfer. • http://forums.grsecurity.net/viewtopic.php?f=3&t=2290 http://git.kernel.org/?p=linux/kernel/git/linville/wireless-2.6.git%3Ba=commit%3Bh=42da2f948d949efd0111309f5827bf0298bcc9a4 http://grsecurity.net/~spender/wireless-infoleak-fix2.patch http://lists.opensuse.org/opensuse-security-announce/2010-11/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2011-02/msg00000.html http://lkml.org/lkml/2010/8/27/413 http://lkml.org/lkml/2010/8/30/127 http://lkml.org/lkml • CWE-193: Off-by-one Error •
CVE-2010-2954
https://notcve.org/view.php?id=CVE-2010-2954
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 •
CVE-2009-4895 – kernel: tty->pgrp races
https://notcve.org/view.php?id=CVE-2009-4895
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.

CVE-2010-2798 – kernel: gfs2: rename causes kernel panic
https://notcve.org/view.php?id=CVE-2010-2798
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 •
