Description Andrej Nemec 2017-06-15 05:34:01 EDT
Document Liberation Project libmwaw has an out-of-bounds write caused by a heap-based buffer overflow related to the MsWrd1Parser::readFootnoteCorrespondance function in lib/MsWrd1Parser.cxx.



Upstream patch:

Comment 1 Andrej Nemec 2017-06-15 05:34:45 EDT
Created libmwaw tracking bugs for this issue:

Affects: fedora-all [bug 1461763]
Comment 3 Stefan Cornelius 2017-06-29 09:48:12 EDT
This can result in a heap-based memory corruption. By tricking a user into opening a specially crafted Microsoft Word document in an application using libmwaw, an attacker could possibly use this flaw to execute arbitrary code with the privileges of the user opening the file.
