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 •

The eCryptfs subsystem in the Linux kernel before 3.18 allows local users to gain privileges via a large filesystem stack that includes an overlayfs layer, related to fs/ecryptfs/main.c and fs/overlayfs/super.c. El subsistema eCryptfs en el kernel de Linux en versiones anteriores a 3.18 permite a los usuarios locales obtener privilegios a través de una pila de archivos grande que incluye una capa de superposición, relacionada con fs/ecryptfs/main.c y fs/overlayfs/super.c. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=69c433ed2ecd2d3264efd7afec4439524b319121 http://source.android.com/security/bulletin/2017-04-01.html http://www.securityfocus.com/bid/97354 http://www.securitytracker.com/id/1038201 https://github.com/torvalds/linux/commit/69c433ed2ecd2d3264efd7afec4439524b319121 • CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.8EPSS: 0%CPEs: 13EXPL: 0CVE-2018-5332 – kernel: rds_message_alloc_sgs() function doesn't validate value used during DMA page allocation causes heap out-of-bounds write
https://notcve.org/view.php?id=CVE-2018-5332
In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c). En el kernel de Linux hasta la versión 3.2, la función rds_message_alloc_sgs() no valida un valor empleado durante la asignación de página DMA, lo que conduce a una escritura fuera de límites basada en memoria dinámica (heap), relacionado con la función rds_rdma_extra_size en net/rds/rdma.c In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size() function in 'net/rds/rdma.c') and thus to a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c095508770aebf1b9218e77026e48345d719b17c http://www.securityfocus.com/bid/102507 https://access.redhat.com/errata/RHSA-2018:0470 https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=60daca9efbb3e4109ebc1f7069543e5573fc124e https://github.com/torvalds/linux/commit/c095508770aebf1b9218e77026e48345d719b17c https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://usn.ubuntu.com/3617-1 https://usn. • CWE-787: Out-of-bounds Write •

The get_endpoints function in drivers/usb/misc/usbtest.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device. La función get_endpoints en drivers/usb/misc/usbtest.c en el kernel de Linux, en versiones hasta la 4.13.11, permite que los usuarios locales provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado del sistema) o, posiblemente, causen otros impactos no especificados mediante llamadas del sistema manipuladas. • https://github.com/torvalds/linux/commit/7c80f9e4a588f1925b07134bb2e3689335f6c6d8 https://groups.google.com/d/msg/syzkaller/l3870gs3LhA/y79DYQdFBAAJ https://lists.debian.org/debian-lts-announce/2017/12/msg00004.html https://usn.ubuntu.com/3617-1 https://usn.ubuntu.com/3617-2 https://usn.ubuntu.com/3617-3 https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/3754-1 • CWE-476: NULL Pointer Dereference •
