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 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
