Secunia Research has discovered a vulnerability Adobe Reader, which can be exploited by malicious people to compromise a user’s system. The vulnerability is caused due to a boundary error in the processing of JBIG2 streams. This can be exploited to cause a heap-based buffer overflow via a specially crafted PDF file containing a malformed JBIG2 symbol dictionary segment. Successful exploitation may allow execution of arbitrary code. Adobe Reader versions 8.1.3 and 9.0.0 are affected.
