Secunia Research has discovered a vulnerability in Adobe Reader, which can be exploited by malicious people to compromise a user’s system. The vulnerability is caused by an array-indexing error in AcroForm.api when parsing GIF image data. This can be exploited to bypass a size check to cause a heap-based buffer overflow when a specially crafted PDF file is opened. Successful exploitation may allow execution of arbitrary code. Version 9.3.2 is affected.
