CVE-2016-3707 – kernel-rt: Sending SysRq command via ICMP echo request
https://notcve.org/view.php?id=CVE-2016-3707
The icmp_check_sysrq function in net/ipv4/icmp.c in the kernel.org projects/rt patches for the Linux kernel, as used in the kernel-rt package before 3.10.0-327.22.1 in Red Hat Enterprise Linux for Real Time 7 and other products, allows remote attackers to execute SysRq commands via crafted ICMP Echo Request packets, as demonstrated by a brute-force attack to discover a cookie, or an attack that occurs after reading the local icmp_echo_sysrq file. La función icmp_check_sysrq en net/ipv4/icmp.c en los kernel.org projects/rt patches para el kernel de Linux, tal como se utiliza en el paquete kernel-rt en versiones anteriores a 3.10.0-327.22.1 en Red Hat Enterprise Linux for Real Time 7 y otros productos, permite a atacantes remotos ejecutar comandos SysRq a través de paquetes ICMP Echo Request manipulados, como demuestra un ataque de fuerza bruta para descubrir una cookie, o un ataque que ocurra después de leer el archivo local icmp_echo_sysrq. A flaw was found in the way the realtime kernel processed specially crafted ICMP echo requests. A remote attacker could use this flaw to trigger a sysrql function based on values in the ICMP packet, allowing them to remotely restart the system. Note that this feature is not enabled by default and requires elevated privileges to be configured. • http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://www.openwall.com/lists/oss-security/2016/05/17/1 https://access.redhat.com/errata/RHSA-2016:1301 https://access.redhat.com/errata/RHSA-2016:1341 https://bugzilla.redhat.com/show_bug.cgi?id=1327484 https://access.redhat.com/security/cve/CVE-2016-3707 • CWE-284: Improper Access Control CWE-312: Cleartext Storage of Sensitive Information •
CVE-2016-4805
https://notcve.org/view.php?id=CVE-2016-4805
Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions. Vulnerabilidad de uso después de liberación de memoria en drivers/net/ppp/ppp_generic.c en el kernel de Linux en versiones anteriores a 4.5.2 permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída de sistema o spinlock) o posiblemente tener otro impacto no especificado eliminando una red namespace, relacionado con las funciones ppp_register_net_channel y ppp_unregister_channel. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1f461dcdd296eecedaffffc6bae2bfa90bd7eb89 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org • CWE-416: Use After Free •
CVE-2016-4486 – Linux Kernel 4.4 - 'rtnetlink' Stack Memory Disclosure

The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message. La función rtnl_fill_link_ifmap en net/core/rtnetlink.c en el kernel de Linux en versiones anteriores a 4.5.5 no inicializa una estructura de datos determinada, lo que permite a usuarios locales obtener información sensible del kernel de memoria de pila leyendo un mensaje Netlink. • https://www.exploit-db.com/exploits/46006 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5f8e44741f9f216e33736ea4ec65ca9ac03036e6 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2016-4569 – kernel: Information leak in Linux sound module in timer.c
https://notcve.org/view.php?id=CVE-2016-4569
The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface. La función snd_timer_user_params en sound/core/timer.c en el kernel de Linux hasta la versión 4.6 no inicializa una estructura de datos determinada, lo que permite a usuarios locales obtener información sensible del kernel de memoria de pila a través del uso manipulado de la interfaz ALSA timer. A vulnerability was found in Linux kernel. There is an information leak in file "sound/core/timer.c" of the latest mainline Linux kernel, the stack object “tread” has a total size of 32 bytes. It contains a 8-bytes padding, which is not initialized but sent to user via copy_to_user(), resulting a kernel leak. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cec8f96e49d9be372fdb0c3836dcf31ec71e457e http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-665: Improper Initialization •
