Title: CVE-2014-3693 Use-After-Free in socket manager of Impress Remote

Announced: November  05, 2014

Fixed in: LibreOffice 4.2.7/4.3.3


In LibreOffice 4.0.0 and later, a new feature was added for remote control capabilities in Impress. Users can run a smart phone
application to communicate with Impress over a custom protocol to switch slides and the like. By default whenever Impress is started, it immediately began listening on TCP port 1599 on all interfaces.

But there was a use after free bug in the code managing that port leaving LibreOffice vulnerable to  external attackers with access to that port where those external attackers could cause the deleted port manager to continue to process attacker supplied data.

All users are recommended to upgrade to LibreOffice 4.2.7 or 4.3.3.

The impress remote can be disabled by:

1. Open LibreOffice, go to "Tools -> Options..."
2. Select "LibreOffice Impress -> General"
3. Uncheck "Presentation -> Enable remote control"

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

I'm preparing a bump of Libreoffice, for this bug and for the Boost 1.56 build fix from bug 522178.

CVE-2014-3693 (
  Use-after-free vulnerability in the socket manager of Impress Remote in
  LibreOffice 4.x before 4.2.7 and 4.3.x before 4.3.3 allows remote attackers
  to cause a denial of service (crash) or possibly execute arbitrary code via
  a crafted request to TCP port 1599.
Comment 3 Andreas K. Hüttel archtester gentoo-dev 2014-12-29 21:29:38 UTC
I have bumped LibreOffice, which is a stable branch bugfix release and addresses (amongst other things) this issue. 

Since all my machines run 4.3 and I can't downgrade, this is a blind bump, only build-tested.

Arches please TEST (i.e., build, run, play with it for a while) and stabilize


Target: amd64 x86

NOTE: for libreoffice-bin, this depends >> only on x86 << still on bug 523164 (poppler and icu stabilization) and bug 525286 (boost stabilization), both long pending...
