Allok Fast AVI MPEG Splitter 1.2 contains a stack based buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying a malicious license name string. Attackers can craft a payload with 780 bytes of junk data followed by structured shellcode and place it in the License Name field to trigger the overflow and execute code with application privileges.
