CVSS: 7.0EPSS: 0%CPEs: 8EXPL: 0CVE-2016-10200 – kernel: l2tp: Race condition in the L2TPv3 IP encapsulation feature
https://notcve.org/view.php?id=CVE-2016-10200
Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel before 4.8.14 allows local users to gain privileges or cause a denial of service (use-after-free) by making multiple bind system calls without properly ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c. Condición de carrera en la característica L2TPv3 IP Encapsulation en el kernel de Linux en versiones anteriores a 4.8.14 permite a usuarios locales obtener privilegios o provocar una denegación de servicio (uso después de liberación) realizando múltiples llamadas al sistema enlazadas sin comprobar adecuadamente si un socket tiene el estatus SOCK_ZAPPED, relacionado con net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c. A use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=32c231164b762dddefa13af5a0101032c70b50ef http://source.android.com/security/bulletin/2017-03-01.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.8.14 http://www.securityfocus.com/bid/101783 http://www.securitytracker.com/id/1037965 http://www.securitytracker.com/id/1037968 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com&#x • CWE-264: Permissions, Privileges, and Access Controls CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

net/sctp/socket.c in the Linux kernel through 4.10.1 does not properly restrict association peel-off operations during certain wait states, which allows local users to cause a denial of service (invalid unlock and double free) via a multithreaded application. NOTE: this vulnerability exists because of an incorrect fix for CVE-2017-5986. net/sctp/socket.c en el kernel de Linux en versiones hasta 4.10.1 no restringe adecuadamente las operaciones de despegue de la asociación durante varios estados de espera, lo que permite a usuarios locales provocar una denegación de servicio (desbloqueo no válido y liberación doble) a través de una aplicación multihilo. NOTA: esta vulnerabilidad existe debido a una solución incorrecta de CVE-2017-5986. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=dfcb9f4f99f1e9a49e43398a7bfbf56927544af1 http://www.debian.org/security/2017/dsa-3804 http://www.openwall.com/lists/oss-security/2017/02/27/2 http://www.securityfocus.com/bid/96473 https://github.com/torvalds/linux/commit/dfcb9f4f99f1e9a49e43398a7bfbf56927544af1 • CWE-415: Double Free •
