Comment 2 Ratul Gupta 2014-01-09 09:40:57 UTC

Created graphviz tracking bugs for this issue:

Affects: fedora-all [bug 1050873]
Affects: epel-5 [bug 1050874]

Comment 5 Vincent Danen 2014-01-09 20:26:48 UTC

This issue would affect graphviz in Fedora and EPEL testing because they would have used the initial patch for CVE-2014-0978.  It does not affect Red Hat Enterprise Linux 6.


Statement:

Not vulnerable. This issue did not affect the versions of graphviz as shipped with Red Hat Enterprise Linux 6 as it did not include the patch that introduced this flaw.

Comment 7 Fedora Update System 2014-02-11 19:16:03 UTC

graphviz-2.12-10.el5 has been pushed to the Fedora EPEL 5 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 8 Fedora Update System 2014-02-11 22:59:34 UTC

graphviz-2.34.0-8.fc20 has been pushed to the Fedora 20 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 9 Fedora Update System 2014-02-11 23:01:37 UTC

graphviz-2.30.1-12.fc19 has been pushed to the Fedora 19 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 10 Tomas Hoger 2015-05-20 11:14:03 UTC

This is mitigated by FORTIFY_SOURCE to an application abort (for further explanation see bug 1049165 comment 21 for the original CVE-2014-0978).  Hence reducing impact rating.
