Description Andrej Nemec 2017-10-31 08:21:19 UTC 
An exploitable out-of-bounds write vulnerability exists in the WW8RStyle::ImportOldFormatStyles functionality of Apache OpenOffice 4.1.3. A specially crafted doc file can cause a out-of-bounds write resulting in arbitrary code execution. An attacker can send/provide malicious doc file to trigger this vulnerability.

Comment 1 Andrej Nemec 2017-10-31 08:23:14 UTC 
Created libreoffice tracking bugs for this issue:

Affects: fedora-all [bug 1507808]
Comment 2 David Tardon 2017-10-31 08:47:24 UTC 
Most likely fixed by https://gerrit.libreoffice.org/gitweb?p=core.git;a=commitdiff_plain;h=42a709d1ef647aab9a1c9422b4e25ecaee857aba , which would mean no Fedora version is vulnerable. Is there any reproducer?
Comment 3 David Tardon 2017-10-31 09:07:05 UTC 
Caolan confirms this is fixed by the mentioned commit, so no current Fedora is vulnerable.
Comment 4 Huzaifa S. Sidhpurwala 2017-10-31 09:24:49 UTC 
As per LibreOffice upstream advisory mentioned in comment 0, this issue is fixed in version 5.0.2, hence only the version shipped with Red Hat Enterprise Linux 6 is vulnerable.
