Description Vincent Danen 2014-12-03 14:36:30 UTC

Michal Zalewski reported [1] an out-of-bounds memory access vulnerability in unrtf.  Processing a malformed RTF file could lead to a segfault while accessing a pointer that may be under the attacker's control.  This would lead to a denial of service (application crash) or, potentially, the execution of arbitrary code.

Hanno Böck also reported [2] a number of other crashes in unrtf.

There has been no response upstream regarding this (it seems that unrtf is no longer being maintained) so there is no patch available as of yet.

Comment 2 Vincent Danen 2014-12-03 14:41:15 UTC

Created unrtf tracking bugs for this issue:

Affects: fedora-all [bug 1170235]
Affects: epel-6 [bug 1170236]
Affects: epel-7 [bug 1170237]

Comment 3 Vincent Danen 2014-12-04 14:41:33 UTC

This likely will require more than one CVE, but we'll see what MITRE says/does.  Mentioning both reports here is ok as there are no patches available for any of it.

Comment 4 Martin Prpič 2014-12-05 13:19:17 UTC

MITRE assigned two CVEs (CVE-2014-9274, CVE-2014-9275) to these issues:

http://seclists.org/oss-sec/2014/q4/904

Comment 5 Ken Dreyer 2014-12-17 18:28:25 UTC

Jean-Francois Dockes proposed fixes for both CVEs.

CVE-2014-9274 is addressed by
https://lists.gnu.org/archive/html/bug-unrtf/2014-12/msg00000.html

CVE-2014-9275 is addressed by
https://lists.gnu.org/archive/html/bug-unrtf/2014-12/msg00001.html

All three changes were incorporated upstream and shipped as a part of unrtf 0.21.6. (http://hg.savannah.gnu.org/hgweb/unrtf/rev/891c2f431c90)

So we should just push the newer version (0.21.6 or later) to all Fedora and EPEL branches.

Comment 6 Fedora Update System 2015-01-03 00:12:44 UTC

unrtf-0.21.7-1.el6 has been pushed to the Fedora EPEL 6 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 7 Fedora Update System 2015-01-03 00:14:39 UTC

unrtf-0.21.7-1.el7 has been pushed to the Fedora EPEL 7 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 8 Fedora Update System 2015-01-03 19:04:06 UTC

unrtf-0.21.7-1.fc21 has been pushed to the Fedora 21 stable repository.  If problems still persist, please make note of it in this bug report.
