remote code execution in xpdf, kdegraphics3-pdf, koffice, libextractor,

Secunia Research reported three security bugs in xpdf. The first problem occurs while indexing an array in DCTStream:: readProgressiveDataUnit() and is tracked by CVE-2007-4352. Another method in the same class named reset() is vulnerable to an integer overflow which leads to an overflow on the heap, CVE-2007-5392. The last bug also causes an overflow on the heap but this time in method lookChar() of class CCITTFaxStream, CVE-2007-5393. All three bugs can be exploited remotely with a crafted PDF file with user- assistance only. These bugs do not only affect xpdf but also the following packages: kdegraphics3-pdf, koffice, libextractor, poppler, gpdf, cups, pdf, pdftohtml
