Hi,

As discussed in oss-security[1], libapache-sessionx-perl uses a poor
source of entropy in Apache::Session::Generate::MD5. The critical part
is moving away from rand (e.g. to using urandom), but it would also be
a good time to update the way the id is generated.

The details are in the oss-sec thread.

AFAICS libapache-sessionx-perl only exists to support libembperl-perl.
As we're not going to ship libembperl-perl in trixie due to #1042845,
I wonder if we should remove libapache-sessionx-perl from testing too?

Alternatively, the approach taken for libapache-session-perl #930659
(using Crypt::URandom) seems easy to apply here as well.

Agreed.
I'm raising the severity to trigger the auto-removal from testing.

Ack, if someone is interested in the package; otherwise just getting
it out of testing seems fine to me.
