DESCRIPTION:
shinnai has discovered a vulnerability in Haihaisoft PDF Reader,
which can be exploited by malicious people to compromise a user's
system.

The vulnerability is caused due to a boundary error in
PDFReaderOCX.ocx when parsing the "URL" property and can be exploited
to cause a stack-based buffer overflow.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in PDFReaderOCX.ocx version 1.1.2.0
bundled with Haihaisoft PDF Reader version 1.1.5.0. Other versions
may also be affected.
