Hi,

The following vulnerability was published for jetty9.

CVE-2021-34429[0]:
| For Eclipse Jetty versions 9.4.37-9.4.42, 10.0.1-10.0.5 &
| 11.0.1-11.0.5, URIs can be crafted using some encoded characters to
| access the content of the WEB-INF directory and/or bypass some
| security constraints. This is a variation of the vulnerability

Please adjust the affected versions in the BTS as needed. Just from
the upstream versions it is considered to be a problem starting with
9.4.37, but I have *not* checked if we might have an earlier patch
introducing the issue, so please double check, but I suspect the only
version so far affected is the one in bullseye/sid.

Regards,
Salvatore
