Subject: BUG/CRITICAL: mux-h2: re-check the frame length when PRIORITY is used
MIME-Version: 1.0
Content-Type: text/plain; charset=latin1
Content-Transfer-Encoding: 8bit
Tim Düsterhus reported a possible crash in the H2 HEADERS frame decoder
when the PRIORITY flag is present. A check is missing to ensure the 5
extra bytes needed with this flag are actually part of the frame. As per
RFC7540#4.2, let's return a connection error with code FRAME_SIZE_ERROR.
Many thanks to Tim for responsibly reporting this issue with a working
config and reproducer. This issue was assigned CVE-2018-20615.
This fix must be backported to 1.9 and 1.8.

Subject: BUG/CRITICAL: hpack: never index a header into the headroom after
wrapping
The HPACK header table is implemented as a wrapping list inside a contigous
area. Headers names and values are stored from right to left while indexes
are stored from left to right. When there's no more room to store a new one,
we wrap to the right again, or possibly defragment it if needed. The condition
do use the right part (called tailroom) or the left part (called headroom)
depends on the location of the last inserted header. After wrapping happens,
the code forces to stick to tailroom by pretending there's no more headroom,
so that the size fit test always fails. The problem is that nothing prevents
from storing a header with an empty name and empty value, resulting in a
total size of zero bytes, which satisfies the condition to use the headroom.
Doing this in a wrapped buffer results in changing the "front" header index
and causing miscalculations on the available size and the addresses of the
next headers. This may even allow to overwrite some parts of the index,
opening the possibility to perform arbitrary writes into a 32-bit relative
address space.
This patch fixes the issue by making sure the headroom is considered only
when the buffer does not wrap, instead of relying on the zero size. This
must be backported to all versions supporting H2, which is as far as 1.8.
Many thanks to Felix Wilhelm of Google Project Zero for responsibly
reporting this problem with a reproducer and a detailed analysis.

Subject: [PATCH] BUG/MEDIUM: mworker: fix again copy_argv()
When backporting patch df6c5a8 ("BUG/MEDIUM: mworker: fix the copy of
options in copy_argv()") part of the patch was removed by mistake.
Letting the bug #644 unfixed.
This patch fixes the problem by reintroducing the missing part.
1.8 only, no backport needed.
