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...
