Description

Posadis DNS server contains a flaw that allows a local attacker to create a denial of service that consumes available memory. The issue is due to the pthreads functions not properly deatching threads when they are closed down. An attacker can force the system to create a high number of threads to exhaust system resources and run the system out of memory.

Classification
