There is a use-after-free issue in JBIG2Stream::close() located in JBIG2Stream.cc in Xpdf 4.04. It can be triggered by sending a crafted PDF file to (for example) the pdfimages binary. It allows an attacker to cause Denial of Service or possibly have unspecified other impact.
Add your gear to cvedb and we'll alert you only when xpdfreader ships something exploited.
