CVE-2015-2922 – kernel: denial of service (DoS) attack against IPv6 network stacks due to improper handling of Router Advertisements.
https://notcve.org/view.php?id=CVE-2015-2922
The ndisc_router_discovery function in net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack in the Linux kernel before 3.19.6 allows remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message. La función ndisc_router_discovery en net/ipv6/ndisc.c en la implementación de protocolo Neighbor Discovery (ND) en la pila IPv6 en el kernel de Linux anterior a 3.19.6 permite a atacantes remotos reconfigurar una configuración 'hop-limit' a través de un valor hop_limit pequeño en un mensaje Router Advertisement (RA). It was found that the Linux kernel's TCP/IP protocol suite implementation for IPv6 allowed the Hop Limit value to be set to a smaller value than the default one. An attacker on a local network could use this flaw to prevent systems on that network from sending or receiving network packets. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=6fd99094de2b83d1d4c8457f2c83483b2828e75a http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155804.html http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155854.html http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155908.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00011.html http: • CWE-17: DEPRECATED: Code CWE-454: External Initialization of Trusted Variables or Data Stores •
CVE-2014-8171 – kernel: memcg: OOM handling DoS
https://notcve.org/view.php?id=CVE-2014-8171
The memory resource controller (aka memcg) in the Linux kernel allows local users to cause a denial of service (deadlock) by spawning new processes within a memory-constrained cgroup. El controlador de recursos de memoria (también conocido como memcg) en el kernel de Linux permite que usuarios locales provoquen una denegación de servicio (deadlock) generando nuevos procesos en un cgroup con límite de memoria. It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system. • http://rhn.redhat.com/errata/RHSA-2015-0864.html http://rhn.redhat.com/errata/RHSA-2015-2152.html http://rhn.redhat.com/errata/RHSA-2015-2411.html http://rhn.redhat.com/errata/RHSA-2016-0068.html http://www.securityfocus.com/bid/74293 https://bugzilla.redhat.com/show_bug.cgi?id=1198109 https://access.redhat.com/security/cve/CVE-2014-8171 • CWE-399: Resource Management Errors CWE-833: Deadlock •
CVE-2014-3673 – kernel: sctp: skb_over_panic when receiving malformed ASCONF chunks
https://notcve.org/view.php?id=CVE-2014-3673
The SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (system crash) via a malformed ASCONF chunk, related to net/sctp/sm_make_chunk.c and net/sctp/sm_statefuns.c. La implementación SCTP en el kernel de Linux hasta 3.17.2 permite a atacantes remotos causar una denegación de servicio (caída del sistema) a través de un chunk ASCONF malformado, relacionado con net/sctp/sm_make_chunk.c y net/sctp/sm_statefuns.c. A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled malformed Address Configuration Change Chunks (ASCONF). A remote attacker could use either of these flaws to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=9de7922bc709eee2f609cd01d98aaedc4cf5ea74 http://linux.oracle.com/errata/ELSA-2014-3087.html http://linux.oracle.com/errata/ELSA-2014-3088.html http://linux.oracle.com/errata/ELSA-2014-3089.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html • CWE-20: Improper Input Validation •
CVE-2014-3687 – kernel: net: sctp: fix panic on duplicate ASCONF chunks
https://notcve.org/view.php?id=CVE-2014-3687
The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (panic) via duplicate ASCONF chunks that trigger an incorrect uncork within the side-effect interpreter. La función sctp_assoc_lookup_asconf_ack en net/sctp/associola.c en la implementación SCTP en el kernel de Linux hasta 3.17.2 permite a atacantes remotos causar una denegación de servicio (kernel panic) a través de trozos ASCONF duplicados que provocan una liberación incorrecta dentro del intérprete de efectos secundarios. A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled duplicate Address Configuration Change Chunks (ASCONF).

CVE-2012-2682 – cumin: DoS via displayed link names containing non-ASCII characters
https://notcve.org/view.php?id=CVE-2012-2682
Cumin (aka MRG Management Console), as used in Red Hat Enterprise MRG 2.5, allows attackers with certain database privileges to cause a denial of service (inaccessible page) via a non-ASCII character in the name of a link. Cumin (también conocido como MRG Management Console), utilizado en Red Hat Enterprise MRG 2.5, permite a atacantes con ciertos privilegios en la base de datos causar una denegación de servicio (página inaccesible) a través de un caracter no ASCII en el nombre de un enlace. It was found that if Cumin were asked to display a link name containing non-ASCII characters, the request would terminate with an error. If data containing non-ASCII characters were added to the database (such as via Cumin or Wallaby), requests to load said data would terminate and the requested page would not be displayed until an administrator cleans the database. • http://rhn.redhat.com/errata/RHSA-2014-0858.html http://rhn.redhat.com/errata/RHSA-2014-0859.html https://bugzilla.redhat.com/show_bug.cgi?id=830254 https://access.redhat.com/security/cve/CVE-2012-2682 • CWE-20: Improper Input Validation •
