Summary

content/base/src/nsDocument.cpp in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 does not consider whether WebRTC video sharing is occurring, which allows remote attackers to obtain sensitive information from the local camera in certain IFRAME situations by maintaining a session after the user temporarily navigates away.
