dhcp: unexpected abort caused by a DHCPv6 decline message
The DHCPv6 server in ISC DHCP 4.0.x and 4.1.x before 4.1.2-P1, 4.0-ESV and 4.1-ESV before 4.1-ESV-R1, and 4.2.x before 4.2.1b1 allows remote attackers to cause a denial of service assertion failure and daemon crash by sending a message over IPv6 for a declined and abandoned address...
PT-2010-2540 · Microsoft · Windows
Name of the Vulnerable Software and Affected Versions: Microsoft Windows versions prior to the fixed version Description: A spoofing issue exists due to the way Windows checks the inner packet's IPv6 source address in a tunneled ISATAP packet. This could allow an attacker to impersonate an addres...
kernel: ipv6: fix ip6_dst_lookup_tail() NULL pointer dereference
The ip6dstlookuptail function in net/ipv6/ip6output.c in the Linux kernel before 2.6.27 does not properly handle certain circumstances involving an IPv6 TUN network interface and a large number of neighbors, which allows attackers to cause a denial of service NULL pointer dereference and OOPS or...

Implementations of IPv6 may be vulnerable to denial of service (DoS) attacks
Overview Implementations of Internet Protocol version 6 IPv6 may be vulnerable to denial of service DoS attacks. Implementations of IPv6 contain an issue in the processing of packets related to the Neighbor Discovery Protocol RFC4861, which may lead to a denial of service vulnerablility. For more...
Issue of Access Control Failure in Hitachi Device Manager Server
Overview Hitachi Device Manager servers contain a vulnerability in which access control settings would be rendered invalid in the following cases: - IPv6 format is used for communications between a Hitachi Device Manager server and its clients. - Access controls for Hitachi Device Manager clients...
IPv6 oops triggerable by any user
net/ipv6/tcpipv6.c in Linux kernel 2.6.x up to 2.6.21-rc3 inadvertently copies the ipv6flsocklist from a listening TCP socket to child sockets, which allows local users to cause a denial of service OOPS or double free by opening a listening IPv6 socket, attaching a flow label, and connecting to...
security flaw
The IPv6 URI parsing routines in the apr-util library for Apache 2.0.50 and earlier allow remote attackers to cause a denial of service child process crash via a certain URI, as demonstrated using the Codenomicon HTTP Test Tool...
