CVSS: 8.8EPSS: 0%CPEs: 1EXPL: 0CVE-2016-8650 – kernel: Null pointer dereference via keyctl
https://notcve.org/view.php?id=CVE-2016-8650
The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through 4.8.11 does not ensure that memory is allocated for limb data, which allows local users to cause a denial of service (stack memory corruption and panic) via an add_key system call for an RSA key with a zero exponent. La función mpi_powm en lib/mpi/mpi-pow.c en el kernel Linux hasta la versión 4.8.11 no se asegura que la memoria esté alojada para datos limb, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria de pila y pánico) a través de una llamada de sistema add_key para una llave RSA con un componente cero. A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f5527fffff3f002b0a6b376163613b82f69de073 http://seclists.org/fulldisclosure/2016/Nov/76 http://www.openwall.com/lists/oss-security/2016/11/24/8 http://www.securityfocus.com/bid/94532 http://www.securitytracker.com/id/1037968 https://access.redhat.com/errata/RHSA-2017:0931 https://access.redhat.com/errata/RHSA-2017:0932 https://access.redhat.com/errata/RHSA-2017:0933 https://access.redhat.com/errata/RHSA- • CWE-20: Improper Input Validation CWE-399: Resource Management Errors CWE-476: NULL Pointer Dereference •
