https://notcve.org/view.php?id=CVE-2016-6327
drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel before 4.5.1 allows local users to cause a denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a device write operation. drivers/infiniband/ulp/srpt/ib_srpt.c en el kernel de Linux en versiones anteriores a 4.5.1 permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL y caída de sistema) usando un comando ABORT_TASK para abortar una operación de escritura de dispositivo. System using the infiniband support module ib_srpt were vulnerable to a denial of service by system crash by a local attacker who is able to abort writes to a device using this initiator. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=51093254bf879bc9ce96590400a87897c7498463 http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.1 http://www.openwall.com/lists/oss-security/2016/08/19/5 http://www.securityfocus.com/bid/92549 https://bugzilla.redhat.com/show_bug.cgi?id=1354525 https://github.com/torvalds/linux/commit/51093254bf879bc9c • CWE-476: NULL Pointer Dereference •

fs/overlayfs/copy_up.c in the Linux kernel before 4.2.6 uses an incorrect cleanup code path, which allows local users to cause a denial of service (dentry reference leak) via filesystem operations on a large file in a lower overlayfs layer. fs/overlayfs/copy_up.c en el kernel de Linux en versiones anteriores a 4.2.6 utiliza una ruta de código de limpieza incorrecta, lo que permite a usuarios locales provocar una denegación de servicio (fuga de referencia dentry) a través de operaciones de sistema de archivos en un archivo grande en una capa overlayfs inferior. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ab79efab0a0ba01a74df782eb7fa44b044dae8b5 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.2.6 http://www.openwall.com/lists/oss-security/2016/08/23/9 http://www.securityfocus.com/bid/92611 https://bugzilla.redhat.com/show_bug.cgi?id=1367814 https://github.com/torvalds/linux/commit/ab79efab0a0ba01a74df782eb7fa44b044dae8b5 • CWE-399: Resource Management Errors •
CVSS: 4.4EPSS: 0%CPEs: 1EXPL: 0CVE-2016-7097 – kernel: Setting a POSIX ACL via setxattr doesn't clear the setgid bit
https://notcve.org/view.php?id=CVE-2016-7097
The filesystem implementation in the Linux kernel through 4.8.2 preserves the setgid bit during a setxattr call, which allows local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions. La implementación del sistema de archivos en el kernel de Linux hasta la versión 4.8.2 preserva el bit setgid durante una llamada setxattr, lo que permite a usuarios locales obtener privilegios de grupo aprovechando la existencia de un programa setgid con restricciones en permisos de ejecución. It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=073931017b49d9458aa351605b43a7e34598caef http://marc.info/?l=linux-fsdevel&m=147162313630259&w=2 http://rhn.redhat.com/errata/RHSA-2017-0817.html http://www.openwall.com/lists/oss-security/2016/08/26/3 http://www.securityfocus.com/bid/92659 http://www.securitytracker.com/id/1038201 http://www.spinics.net/lists/linux-fsdevel/msg98328.html http://www.ubuntu.com/usn/USN-3146-1 http://www.ubuntu.com • CWE-285: Improper Authorization CWE-287: Improper Authentication •
