In Xpdf 4.01.01, a heap-based buffer overflow could be triggered in DCTStream::decodeImage() in Stream.cc when writing to frameBuf memory. It can, for example, be triggered by sending a crafted PDF document to the pdftotext tool. It allows an attacker to use a crafted pdf file to cause Denial of Service, an information leak, or possibly unspecified other impact. #### Notes Author| Note ---|--- [jdstrand](<https://launchpad.net/~jdstrand>) | xpdf in koffice is 2.0 [mdeslaur](<https://launchpad.net/~mdeslaur>) | poppler has additional checks and improved logic in the memory allocation function, reproducer doesn't work. [ebarretto](<https://launchpad.net/~ebarretto>) | since 0.5.12-1 libextractor does not use xpdf anymore.
