Common Vulnerabilities and Exposures assigned an identifier CVE-2013-6631 to
the following vulnerability:

Name: CVE-2013-6631
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-6631
Assigned: 20131105
Reference: http://googlechromereleases.blogspot.com/2013/11/stable-channel-update.html
Reference: https://code.google.com/p/chromium/issues/detail?id=296804
Reference: https://code.google.com/p/webrtc/source/detail?r=4827
Reference: https://webrtc-codereview.appspot.com/2275008

Use-after-free vulnerability in the Channel::SendRTCPPacket function
in voice_engine/channel.cc in libjingle in WebRTC, as used in Google
Chrome before 31.0.1650.48 and other products, allows remote attackers
to cause a denial of service (heap memory corruption) or possibly have
unspecified other impact via vectors that trigger the absence of
certain statistics initialization, leading to the skipping of a
required DeRegisterExternalTransport call.
