CVE-2017-14106 – kernel: Divide-by-zero in __tcp_select_window
https://notcve.org/view.php?id=CVE-2017-14106
The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel before 4.12 allows local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path. La función tcp_disconnect en net/ipv4/tcp.c en el kernel de Linux en versiones anteriores a la 4.12 permite que usuarios locales provoquen una denegación de servicio allows local users to cause a denial of service (error __tcp_select_window de división por cero y bloqueo del sistema) desencadenando una desconexión en una ruta de código tcp_recvmsg determinada. A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=499350a5a6e7512d9ed369ed63a4244b6536f4f8 http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://www.debian.org/security/2017/dsa-3981 http://www.securityfocus.com/bid/100878 http://www.securitytracker.com/id/1039549 https://access.redhat.com/errata/RHSA-2017:2918 https://access.redhat.com/errata/RHSA-2017:2930 https://access.redhat.com/errata/RHSA-2017:2931 https://access.redhat.com/er • CWE-369: Divide By Zero •

An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel through 4.12.10 allows local users to cause a denial of service (memory corruption and system crash) by leveraging root access. Un desbordamiento de enteros en la función qla2x00_sysfs_write_optrom_ctl en drivers/scsi/qla2xxx/qla_attr.c en el kernel de Linux hasta la versión 4.12.10 permite que los usuarios locales provoquen una denegación de servicio (corrupción de memoria y fallo de sistema) con acceso root. • http://www.securityfocus.com/bid/100571 https://bugzilla.kernel.org/show_bug.cgi?id=194061 https://lists.debian.org/debian-lts-announce/2017/12/msg00004.html https://patchwork.kernel.org/patch/9929625 https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 • CWE-190: Integer Overflow or Wraparound •

The __skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel before 4.3 does not ensure that n_proto, ip_proto, and thoff are initialized, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a single crafted MPLS packet. función __skb_flow_dissect en net/core/flow_dissector.c en el kernel Linux en versiones anteriores a la 4.3 no garantiza que se inicialicen n_proto, ip_proto y thoff. Esto permite que atacantes remotos provoquen una denegación de servicio (bloqueo del sistema) o que ejecuten código arbitrario mediante un único paquete MPLS manipulado. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a6e544b0a88b53114bfa5a57e21b7be7a8dfc9d0 http://seclists.org/oss-sec/2017/q3/345 http://www.securityfocus.com/bid/100517 https://github.com/torvalds/linux/commit/a6e544b0a88b53114bfa5a57e21b7be7a8dfc9d0 • CWE-665: Improper Initialization •

The acpi_ps_complete_final_op() function in drivers/acpi/acpica/psobject.c in the Linux kernel through 4.12.9 does not flush the node and node_ext caches and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.
