Secunia Research reports:

Secunia Research has discovered some vulnerabilities in Xpdf, which can be exploited by malicious people to compromise a user's system.

• An array indexing error within the "DCTStream::readProgressiveDataUnit()" method in xpdf/Stream.cc can be exploited to corrupt memory via a specially crafted PDF file.
• An integer overflow error within the "DCTStream::reset()" method in xpdf/Stream.cc can be exploited to cause a heap-based buffer overflow via a specially crafted PDF file.
• A boundary error within the "CCITTFaxStream::lookChar()" method in xpdf/Stream.cc can be exploited to cause a heap-based buffer overflow by tricking a user into opening a PDF file containing a specially crafted "CCITTFaxDecode" filter.

Successful exploitation may allow execution of arbitrary code.

The KDE Team reports:

kpdf, the KDE pdf viewer, shares code with xpdf. xpdf contains a vulnerability that can cause a stack based buffer overflow via a PDF file that exploits an integer overflow in StreamPredictor::StreamPredictor(). Remotely supplied pdf files can be used to disrupt the kpdf viewer on the client machine and possibly execute arbitrary code.
