The response function in the JSONP endpoint in WebService/Server/JSONRPC.pm
in jsonrpc.cgi in Bugzilla 3.x and 4.x before 4.0.14, 4.1.x and 4.2.x
before 4.2.10, 4.3.x and 4.4.x before 4.4.5, and 4.5.x before 4.5.5 accepts
certain long callback values and does not restrict the initial bytes of a
JSONP response, which allows remote attackers to conduct cross-site request
forgery (CSRF) attacks, and obtain sensitive information, via a crafted
OBJECT element with SWF content consistent with the _bz_callback character
set.
