Detailed vulnerability description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can create a buffer over-read, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-alljoyn.c by ensuring that a length variable properly tracked the state of a signature variable, pass it to the affected application and perform a denial of service (DoS) attack.
