Integer signedness error in the mobilityoptprint function in the IPv6 mobility printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service out-of-bounds read and crash or possibly execute arbitrary code via a negative length value...

shim: heap-based buffer overflow flaw in IPv6 address parsing

A heap-based buffer overflow flaw was found the way shim parsed certain IPv6 addresses. If IPv6 network booting was enabled, a malicious server could supply a crafted IPv6 address that would cause shim to crash or, potentially, execute arbitrary code...

openstack-neutron: L3-agent denial of service through IPv6 subnet

The L3-agent in OpenStack Neutron before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2 allows remote authenticated users to cause a denial of service IPv4 address attachment outage by attaching an IPv6 private subnet to a L3 router...

Kernel: net: IPv6: panic when UFO=On for an interface

net/ipv6/ip6output.c in the Linux kernel through 3.11.4 does not properly determine the need for UDP Fragmentation Offload UFO processing of small packets after the UFO queueing of a large packet, which allows remote attackers to cause a denial of service memory corruption and system crash or...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 3.11.5 Description: The issue is related to the fib6 add function in the Linux kernel, which does not properly implement error-code encoding. This allows local users with the CAP NET ADMIN capability to cause a...

CVE-2013-5560

The IPv6 implementation in Cisco Adaptive Security Appliance ASA Software 9.1.3 and earlier, when NAT64 or NAT66 is enabled, does not properly process NAT rules, which allows remote attackers to cause a denial of service device reload via crafted packets, aka Bug ID CSCue34342...

CVE-2013-5553

Multiple memory leaks in Cisco IOS 15.1 before 15.14M7 allow remote attackers to cause a denial of service memory consumption or device reload by sending a crafted SIP message over 1 IPv4 or 2 IPv6, aka Bug IDs CSCuc42558 and CSCug25383...

UBUNTU-CVE-2013-4350

The IPv6 SCTP implementation in net/sctp/ipv6.c in the Linux kernel through 3.11.1 uses data structures and function calls that do not trigger an intended configuration of IPsec encryption, which allows remote attackers to obtain sensitive information by sniffing the network...

Kernel: ipv6: using ipv4 vs ipv6 structure during routing lookup in sendmsg

The ip6skdstcheck function in net/ipv6/ip6output.c in the Linux kernel before 3.10 allows local users to cause a denial of service system crash by using an AFINET6 socket for a connection to an IPv4 interface...

DEBIAN-CVE-2013-4162

The udpv6pushpendingframes function in net/ipv6/udp.c in the IPv6 implementation in the Linux kernel through 3.10.3 makes an incorrect function call for pending data, which allows local users to cause a denial of service BUG and system crash via a crafted application that uses the UDPCORK option ...

DEBIAN-CVE-2013-2232

The ip6skdstcheck function in net/ipv6/ip6output.c in the Linux kernel before 3.10 allows local users to cause a denial of service system crash by using an AFINET6 socket for a connection to an IPv4 interface...

DEBIAN-CVE-2012-2744

net/ipv6/netfilter/nfconntrackreasm.c in the Linux kernel before 2.6.34, when the nfconntrackipv6 module is enabled, allows remote attackers to cause a denial of service NULL pointer dereference and system crash via certain types of fragmented IPv6 packets...

DEBIAN-CVE-2010-4563

The Linux kernel, when using IPv6, allows remote attackers to determine whether a host is sniffing the network by sending an ICMPv6 Echo Request to a multicast address and determining whether an Echo Reply is sent, as demonstrated by thcping...

kernel: net: improve sequence number generation

The 1 IPv4 and 2 IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service disrupted networking or hijack network sessions by predicting...

UBUNTU-CVE-2011-4326

The udp6ufofragment function in net/ipv6/udp.c in the Linux kernel before 2.6.39, when a certain UDP Fragmentation Offload UFO configuration is enabled, allows remote attackers to cause a denial of service system crash by sending fragmented IPv6 UDP packets to a bridge device...

kernel: ipv6: make fragment identifications less predictable

The IPv6 implementation in the Linux kernel before 3.1 does not generate Fragment Identification values separately for each destination, which makes it easier for remote attackers to cause a denial of service disrupted networking by predicting these values and sending crafted packets...
