CVSS: 7.8EPSS: 26%CPEs: 12EXPL: 0CVE-2017-7645 – kernel: nfsd: Incorrect handling of long RPC replies
https://notcve.org/view.php?id=CVE-2017-7645
The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. El servidor NFSv2/NFSv3 en el subsistema nfsd en el Kernel de Linux hasta la versión 4.10.11 permite a atacantes remotos provocar una denegación de servicio (caída de sistema) a través de una respuesta RPC larga, relacionada con net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c y fs/nfsd/nfsxdr.c. The NFS2/3 RPC client could send long arguments to the NFS server. These encoded arguments are stored in an array of memory pages, and accessed using pointer variables. Arbitrarily long arguments could make these pointers point outside the array and cause an out-of-bounds memory access. • http://www.debian.org/security/2017/dsa-3886 http://www.securityfocus.com/bid/97950 https://access.redhat.com/errata/RHSA-2017:1615 https://access.redhat.com/errata/RHSA-2017:1616 https://access.redhat.com/errata/RHSA-2017:1647 https://access.redhat.com/errata/RHSA-2018:1319 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e6838a29ecb484c97e4efef9429643b9851fba6e https://github.com/torvalds/linux/commit/e6838a29ecb484c97e4efef9429643b9851fba6e https://help.ecostruxur • CWE-20: Improper Input Validation CWE-130: Improper Handling of Length Parameter Inconsistency •

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 •

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') •
