APP: Digium Asterisk Skinny Client Control Protocol Denial Of Services
This signature detects attempts to exploit a known vulnerability against Digium Asterisk. A successful attack can result in a denial-of-service condition.
Extended Description
An issue was discovered in chan_skinny.c in Asterisk Open Source 13.18.2 and older, 14.7.2 and older, and 15.1.2 and older, and Certified Asterisk 13.13-cert7 and older.
