CVE-2009-1493 is a memory corruption vulnerability in the customDictionaryOpen spell method exposed through the JavaScript API in Adobe Reader 9.1, 8.1.4, 7.1.1, and earlier on Linux and UNIX. The vulnerable method does not safely handle a specially crafted long string supplied as the second argument. A remote attacker can embed malicious JavaScript in a crafted PDF document that invokes customDictionaryOpen() with this malformed argument, triggering memory corruption during processing. The flaw can result in application crash and, under successful exploitation conditions, arbitrary code execution in the context of the user running Adobe Reader.
