Description Huzaifa S. Sidhpurwala 2012-08-27 00:16:22 EDT
Mozilla security researcher Mark Goodwin discovered an issue with the Firefox developer tools' debugger. If remote debugging is disabled, but the experimental HTTPMonitor extension has been installed and enabled, a remote user can connect to and use the remote debugging service through the port used by HTTPMonitor. A remote-enabled flag has been added to resolve this problem and close the port unless debugging is explicitly enabled. 



Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Mozilla security researcher Mark Goodwin as the original reporter of this flaw.


This issue does not affect the version of Firefox and Thunderbird package, as shipped with Red Hat Enterprise Linux 5 and 6.
