Description Marian Rehak 2020-09-08 02:11:25 UTC 
There is an invalid memory access in the function fprintf located in Error.cc in Xpdf 4.0.2. It can be triggered by sending a crafted PDF file to the pdftohtml binary, which allows a remote attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.
