Input validation error in Linux kernel - CVE-2011-3188

Vulnerability details

The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.

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 these values and sending crafted packets.
