Description Andrej Nemec 2017-10-06 05:49:49 EDT 
In Poppler, memory corruption occurs in a call to Object::streamGetChar in Object.h after a repeating series of Gfx::display, Gfx::go, Gfx::execOp, Gfx::opShowText, and Gfx::doShowText calls (aka a Gfx.cc infinite loop). A local attacker could use a maliciously crafted PDF document to crash the application.

This is a different vulnerability than CVE-2017-14919.
