#5533 — APT vulnerability [DSA 4371-1]

SubjectAPT vulnerability [DSA 4371-1]
Message-ID<xj54e-76b-11@gated-at.bofh.it>
Hello everybody,

is this vulnerability affecting also apt-get ?
If yes, will there be another DSA soon?

I'm also encountering many errors when using
 apt -o Acquire::http::AllowRedirect=false update
 apt -o Acquire::http::AllowRedirect=false upgrade

As written in announcement: This is known to break some proxies when
used against security.debian.org.

However I do not use proxy at all. I have problems with jessie/updates,
cdn.debian.net, and http.debian.net

Yes, the vulnerability is in http backend, which is used by apt-get.

> If yes, will there be another DSA soon?

No, because apt-get tool is in the package apt.

Try these URLs: http://cdn-fastly.deb.debian.org/debian, http://cdn-fastly.deb.debian.org/debian-security. The domains cdn.debian.net and http.debian.net are deprecated, use deb.debian.org instead.

Thanks for this info. It seems that jessie needs the above direct URL to
fastly even if not behind proxy (can't use SRV records).
