CVSS: 4.6EPSS: 0%CPEs: 160EXPL: 0CVE-2010-1641 – kernel: GFS2: The setflags ioctl() doesn't check file ownership
https://notcve.org/view.php?id=CVE-2010-1641
The do_gfs2_set_flags function in fs/gfs2/file.c in the Linux kernel before 2.6.34-git10 does not verify the ownership of a file, which allows local users to bypass intended access restrictions via a SETFLAGS ioctl request. La función "do_gfs2_set_flags" en "fs/gfs2/file.c" del kernel de Linux anterior a v2.6.34-git10 no comprueba el propietario del archivo, lo que permite a usuarios locales evitar restricciones de acceso intencionadas a través de peticiones SETFLAGS ioctl. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7df0e0397b9a18358573274db9fdab991941062f http://lists.opensuse.org/opensuse-security-announce/2010-07/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2010-08/msg00000.html http://secunia.com/advisories/40645 http://secunia.com/advisories/43315 http://www.kernel.org/pub/linux/kernel/v2.6/snapshots/incr/patch-2.6.34-git9-git10.bz2 http://www.openwall.com/lists/oss-security/2010/05/25/1 • CWE-264: Permissions, Privileges, and Access Controls •

gfs2 in the Linux kernel 2.6.18, and possibly other versions, does not properly handle when the gfs2_quota struct occupies two separate pages, which allows local users to cause a denial of service (kernel panic) via certain manipulations that cause an out-of-bounds write, as demonstrated by writing from an ext3 file system to a gfs2 file system. gfs2 del kernel de Linux v2.6.18, y posiblemente otras versiones, no funciona adecuadamente cuando la estructura gfs2_quota ocupa dos páginas separadas, lo que permite a usuarios locales provocar una denegación de servicio (kernel panic) a través de ciertas manipulaciones que causan una escritura fuera de los límites, como se ha demostrado escribiendo desde un sistema de ficheros ext3 a un sistema de ficheros gfs2. • http://secunia.com/advisories/43315 http://www.openwall.com/lists/oss-security/2010/04/27/1 http://www.openwall.com/lists/oss-security/2010/04/28/1 http://www.securityfocus.com/archive/1/516397/100/0/threaded http://www.vmware.com/security/advisories/VMSA-2011-0003.html https://bugzilla.redhat.com/show_bug.cgi?id=586006 https://exchange.xforce.ibmcloud.com/vulnerabilities/58839 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A10652 https:&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-399: Resource Management Errors •
