Upstream Bugzilla fixed the following issue:
During the generation of a dependency graph, the code for the HTML image map is generated locally if a local dot installation is used. With escaped HTML characters in a bug summary, it is possible to inject unfiltered HTML code in the map file which the CreateImagemap function generates. This could be used for a cross-site scripting attack.
This issue was fixed in versions 4.2.16, 4.4.11, and 5.0.2.
