The vulnerability allows a remote attacker to cause DoS conditions or execute arbitrary code on the target system.

The weakness exists due to integer overflow when handling malformed files. By sending a specially crafted AVM2 file with a large intrf_count value, a remote attacker can trigger memory corruption and cause the application to crash or execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in denial of service or arbitrary code execution on the vulnerable system.
