The Director module (dirapi.dll) in Adobe Shockwave Player contains a memory-corruption flaw in how it parses the rcsL chunk of Director movie files, where an attacker-controlled field value is used as a pointer offset. An attacker who can get a victim to open a crafted Director movie can execute arbitrary code or cause a denial of service, with no authentication or configuration required beyond the victim processing the malicious file.
