CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-2017-7889 – kernel: mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism
https://notcve.org/view.php?id=CVE-2017-7889
The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c. El subsistema mm en el kernel de Linux hasta la versión 3.2 no aplica adecuadamente el mecanismo de protección CONFIG_STRICT_DEVMEM, lo que permite a usuarios locales leer o escribir en ubicaciones de la memoria del kernel en el primer megabyte (y eludir restricciones de acceso de asignación de slab) a través de una aplicación que abre el archivo /dev/mem, relacionado con arch/x86/mm/init.c y drivers/char/mem.c The mm subsystem in the Linux kernel through 4.10.10 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a4866aa812518ed1a37d8ea0c881dc946409de94 http://www.debian.org/security/2017/dsa-3945 http://www.openwall.com/lists/oss-security/2017/04/16/4 http://www.securityfocus.com/bid/97690 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2669 https://access.redhat.com/errata/RHSA-2018:1854 https://git.kernel.org/pub/ • CWE-391: Unchecked Error Condition CWE-732: Incorrect Permission Assignment for Critical Resource •

Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel through 4.10.9 allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. El manejo incorrecto de los errores en las syscalls set_mempolicy y mbind compat en mm/mempolicy.c en el kernel de Linux hasta la versión 4.10.9 permite a los usuarios locales obtener información confidencial de datos de pila no inicializados al activar el fallo de una determinada operación de mapa de bits.

CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 2CVE-2017-2671 – Linux Kernel - 'ping' Local Denial of Service
https://notcve.org/view.php?id=CVE-2017-2671
The ping_unhash function in net/ipv4/ping.c in the Linux kernel through 4.10.8 is too late in obtaining a certain lock and consequently cannot ensure that disconnect function calls are safe, which allows local users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a socket system call. En LightDM en versiones hasta 1.22.0, un problema de directorio transversal en debian/guest-account.sh permite a atacantes locales allows local attackers poseer ubicaciones de ruta de directorio arbitrarias y escalar privilegios a raíz cuando el usuario invitado se cierra. A race condition leading to a NULL pointer dereference was found in the Linux kernel's Link Layer Control implementation. A local attacker with access to ping sockets could use this flaw to crash the system. The Linux kernel suffers from a ping local denial of service vulnerability. • https://www.exploit-db.com/exploits/42135 https://github.com/homjxi0e/CVE-2017-2671 http://openwall.com/lists/oss-security/2017/04/04/8 http://www.securityfocus.com/bid/97407 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2669 https://access.redhat.com/errata/RHSA-2018:1854 https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/net/ipv4/ping.c?id=43a6 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

A missing authorization check in the fscrypt_process_policy function in fs/crypto/policy.c in the ext4 and f2fs filesystem encryption support in the Linux kernel before 4.7.4 allows a user to assign an encryption policy to a directory owned by a different user, potentially creating a denial of service. Una comprobación de autorización que falta en la función fscrypt_process_policy en fs/crypto/policy.c en el soporte de cifrado del sistema de archivos ext4 y f2fs en el kernel de Linux en versiones anteriores a 4.7.4 permite a un usuario asignar una política de cifrado a un directorio propiedad de un usuario diferente, potencialmente creando una denegación de servicio. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=163ae1c6ad6299b19e22b4a35d5ab24a89791a98 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.7.4 http://www.securityfocus.com/bid/97404 https://github.com/torvalds/linux/commit/163ae1c6ad6299b19e22b4a35d5ab24a89791a98 • CWE-264: Permissions, Privileges, and Access Controls •
