Description Sam Fowler 2018-01-05 04:29:08 UTC 
libpoppler in poppler version 0.60.1 is vulnerable to an invalid read and subsequent crash when parsing a specially crafted PDF. The invalid read is caused by incorrect boundary validation in TextOutputDev.cc:TextPool::addWord(), leading to overflow in subsequent calculations.

Analysis:

This is really an OOB read when trying to render specially-crafted text in a PDF file. No remote code execution.
