CVE-2014-3631 – Linux Kernel 3.16.3 - Associative Array Garbage Collection Crash (PoC)
https://notcve.org/view.php?id=CVE-2014-3631
The assoc_array_gc function in the associative-array implementation in lib/assoc_array.c in the Linux kernel before 3.16.3 does not properly implement garbage collection, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via multiple "keyctl newring" operations followed by a "keyctl timeout" operation. La función assoc_array_gc en la implementación associative-array en lib/assoc_array.c en el kernel de Linux anterior a 3.16.3 no implementa debidamente la recolección de basura, lo que permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo y caída del sistema) o posiblemente tener otro impacto no especificado a través de múltiples operaciones 'keyctl newring' seguidas de una operación 'keyctl timeout'. A flaw was found in the way the Linux kernel's keys subsystem handled the termination condition in the associative array garbage collection functionality. A local, unprivileged user could use this flaw to crash the system. • https://www.exploit-db.com/exploits/36268 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=95389b08d93d5c06ec63ab49bd732b0069b7c35e http://osvdb.org/show/osvdb/111298 http://www.exploit-db.com/exploits/36268 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.3 http://www.securityfocus.com/bid/70095 http://www.ubuntu.com/usn/USN-2378-1 http://www.ubuntu.com/usn/USN-2379-1 https://bugzilla.redhat.com/show_bug.cgi?id=11403 •
CVE-2014-3182 – Kernel: HID: logitech-dj OOB array access
https://notcve.org/view.php?id=CVE-2014-3182
Array index error in the logi_dj_raw_event function in drivers/hid/hid-logitech-dj.c in the Linux kernel before 3.16.2 allows physically proximate attackers to execute arbitrary code or cause a denial of service (invalid kfree) via a crafted device that provides a malformed REPORT_TYPE_NOTIF_DEVICE_UNPAIRED value. Error en el indice del arry en la función logi_dj_raw_event en drivers/hid/hid-logitech-dj.c en el kernel de Linux anterior a 3.16.2 permite a atacantes físicamente próximos ejecutar código arbitrario o causar una denegación de servicio (kfree inválido) a través de un dispositivo manipulado que proporciona un valor REPORT_TYPE_NOTIF_DEVICE_UNPAIRED malformado. An out-of-bounds read flaw was found in the way the Logitech Unifying receiver driver handled HID reports with an invalid device_index value. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ad3e14d7c5268c2e24477c6ef54bbdf88add5d36 http://rhn.redhat.com/errata/RHSA-2014-1318.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.2 http://www.openwall.com/lists/oss-security/2014/09/11/21 http://www.securityfocus.com/bid/69770 https://bugzilla.redhat.com/show_bug.cgi?id=1141210 https://code.google.com/p/google-security-research/issues/detail?id=89 https://github.com/t • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly consider the possibility of kmalloc failure, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a long unencrypted auth ticket. net/ceph/auth_x.c en Ceph, utilizado en el kernel de Linux anterior a 3.16.3, no considera debidamente la posibilidad de fallos de kmalloc, lo que permite a atacantes remotos causar una denegación de servicio (caída del sistema) o posiblemente tener otro impacto no especificado a través de un ticket de autor largo no cifrado. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c27a3e4d667fdcad3db7b104f75659478e0c68d8 http://tracker.ceph.com/issues/8979 http://tracker.ceph.com/issues/9560 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.3 http://www.openwall.com/lists/oss-security/2014/09/15/7 http://www.ubuntu.com/usn/USN-2376-1 http://www.ubuntu.com/usn/USN-2377-1 http://www.ubuntu.com/usn/USN-2378-1 http://www.ubuntu.com/usn/USN • CWE-399: Resource Management Errors •
CVE-2014-6410 – kernel: udf: Avoid infinite loop when processing indirect ICBs
https://notcve.org/view.php?id=CVE-2014-6410
The __udf_read_inode function in fs/udf/inode.c in the Linux kernel through 3.16.3 does not restrict the amount of ICB indirection, which allows physically proximate attackers to cause a denial of service (infinite loop or stack consumption) via a UDF filesystem with a crafted inode. La función __udf_read_inode en fs/udf/inode.c en el kernel de Linux hasta 3.16.3 no restringe la cantidad de indirección ICB, lo que permite a atacantes físicamente próximos causar una denegación de servicio (bucle infinito o consumo de la pila) a través de un sistema de ficheros UDF con un inodo manipulado. A stack overflow flaw caused by infinite recursion was found in the way the Linux kernel's Universal Disk Format (UDF) file system implementation processed indirect Information Control Blocks (ICBs). An attacker with physical access to the system could use a specially crafted UDF image to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c03aa9f6e1f938618e6db2e23afef0574efeeb65 http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00007.html http://marc.info/?l=bugtraq&m=142722450701342&w=2 http://marc.info/?l=bugtraq&m=142722544401658&w=2 http://rhn.redhat.com/errata/RHSA-2014-1318.html http://www.openwall.com/lists/oss-security/2014/09/15/9 http: • CWE-399: Resource Management Errors CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
