Some vulnerabilities have been reported in Poppler, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise an application using the library.
1) An error in "Gfx::getPos()" can be exploited to dereference an uninitialised pointer.
2) An array indexing error exists when parsing Type1 fonts in "FoFiType1::parse()", which can be exploited to corrupt memory via a specially crafted PDF file.
3) Other vulnerabilities are caused due to e.g. memory leak errors, which can be exploited to cause a crash by e.g. tricking a user opening a specially crafted PDF file in an application using the library.
4) An error within the "Gfx" class when handling untrusted command streams can be exploited to cause a memory corruption by tricking a user into opening a specially crafted PDF file in an application using the library.
Solution: Update to version 0.16.0.
