Integer overflow in the ActionScript Virtual Machine 2 (AVM2) abcFile parser in Adobe Flash Player before 9.0.246.0 and 10.x before 10.0.32.18, and Adobe AIR before 1.5.2, allows attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an AVM2 file with a large intrf_count value that triggers a dereference of an out-of-bounds pointer.
