Subject: CVE request: 3 DoS conditions in Rake
Three issues were noted in recent release of upstream Rake. All are DoS
issues.
From https://bugzilla.redhat.com/show_bug.cgi?id=895277 (2 issues):
Upstream released [1] Rack 1.4.2, 1.3.7, 1.2.6, and 1.1.4 to fix a
denial of service condition when Rack parses content with a certain
Content-Disposition header as noted in the original report [2].
This has been fixed in git [3].
Additionally, a second flaw that was fixed in 1.4.4, 1.3.9, 1.2.7, and
1.1.5 was also announced [4] that creates a minor denial of service
condition, this time in the Rack::Auth::AbstractRequest, where it
symbolized arbitrary strings (apparently this has something to do with
authentication, but there is no further information provided other than
the fix [5] itself, which is noted as "a breaking API change").

And from https://bugzilla.redhat.com/show_bug.cgi?id=895282:
Upstream released [1] Rack 1.4.3 and 1.3.8 to fix a denial of service
condition due to a malicious client sending excessively long lines that
trigger an out-of-memory error in Rack.
This has been fixed in git [2].

Could three CVEs be assigned for these issues please? Thanks.
