Description


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.

Provided and/or discovered by:
1-3) Joel Voss, Leviathan Security Group
4) David Benjamin. Security impact reported by Dan Rosenberg.
