In PoDoFo 0.9.5, there exists a heap-based buffer over-read vulnerability in UnescapeName() in PdfName.cpp. Remote attackers could leverage this vulnerability to cause a denial-of-service or possibly unspecified other impact via a crafted pdf file.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
