What is CVE-2007-3380?
CVE-2007-3380 is a medium-severity denial of service vulnerability in Linux kernel, published on 20 Jul 2007. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Distributed Lock Manager (DLM) in the cluster manager for Linux kernel 2.6.15 allows remote attackers to cause a denial of service (loss of lock services) by connecting to the DLM port, which probably prevents other processes from accessing the service.
