CVSS: 8.1EPSS: 2%CPEs: 4EXPL: 0CVE-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 •

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 •
