Comment 6 for bug 39580

Firefox 1.5.0.2 (or the individual security updates) will make it into 6.06 for the release. (to resolve security issues)
Since this is a Development version of ubuntu, security updates hold a similar priority to normal bugs.
The maintainer is likely to update to 1.5.0.2 to cover All the fixed bugs.

Filing individual bugs for each individual security issue would just be a waste because this bug allready covers them.
