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 •
CVE-2010-2226 – kernel: xfs swapext ioctl minor security issue
https://notcve.org/view.php?id=CVE-2010-2226
The xfs_swapext function in fs/xfs/xfs_dfrag.c in the Linux kernel before 2.6.35 does not properly check the file descriptors passed to the SWAPEXT ioctl, which allows local users to leverage write access and obtain read access by swapping one file into another file. La función xfs_swapext en fs/xfs/xfs_dfrag.c en el kernel de Linux kernel anterior v2.6.35 no chequea adecuadamente los descriptores de archivo en SWAPEXT ioctl, lo que permiete a usuarios locales aprovechar el acceso de escritura y obtener acceso de lectura por intercambio de un fichero en otro fichero. • http://archives.free.net.ph/message/20100616.130710.301704aa.en.html http://archives.free.net.ph/message/20100616.135735.40f53a32.en.html http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1817176a86352f65210139d4c794ad2d19fc6b63 http://lists.opensuse.org/opensuse-security-announce/2010-12/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2011-02/msg00000.html http://marc.info/?l=oss-security&m=127677135609357&w=2 http://marc.info/?l=oss-security& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
