CVE-2019-12957 (GCVE-0-2019-12957)

Vulnerability from cvelistv5 – Published: 2019-06-24 23:27 – Updated: 2024-08-04 23:32

Summary

In Xpdf 4.01.01, a buffer over-read could be triggered in FoFiType1C::convertToType1 in fofi/FoFiType1C.cc when the index number is larger than the charset array bounds. It can, for example, be triggered by sending a crafted PDF document to the pdftops 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.
