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.

jdstrand | xpdf in koffice is 2.0 |
mdeslaur | poppler has additional checks and improved logic in the memory allocation function, reproducer doesn’t work. |
ebarretto | since 0.5.12-1 libextractor does not use xpdf anymore. xpdf in Debian uses poppler, which is not affected or fixed |
