Description Dhananjay Arunesh 2019-07-08 05:06:22 UTC 
In Xpdf 4.01.01, a heap-based buffer over-read could be triggered in strncpy from FoFiType1::parse in fofi/FoFiType1.cc because it does not ensure the source string has a valid length before making a fixed-length copy. 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 or an information leak, or possibly have unspecified other impact.
