Description Laura Pardo 2018-02-22 20:27:14 UTC

A flaw was discovered in Asterisk 13.x, 14.x, 15.x and 13.18. A crash occurs when a number of authenticated INVITE messages are sent over TCP or TLS and then the connection is suddenly closed. This issue leads to a segmentation fault and allows an attacker to perform a Denial of Service (DoS) attack.
