DoS (Denial of Service)
This includes vulnerabilities ranging from excessive resource consumption (e.g. causing a system to use a lot of memory) to crashing an application or an entire system.
IOActive has discovered a vulnerability in FreeBSD, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to a NULL pointer dereference error when handling ASCONF chunks and can be exploited to cause a kernel panic via a specially crafted verification tag sent in a SCTP packet.
The vulnerability is confirmed in version 8.1. Other versions may also be affected.
No official solution is currently available.
