Description Dhananjay Arunesh 2019-04-04 07:55:29 UTC

An out-of-bounds heap write condition may occur when scanning OLE2 files such as Microsoft Office 97-2003 documents. The invalid write happens when an invalid pointer is mistakenly used to initialize a 32bit integer to zero. This is likely to crash the application.
