Hi,
HAProxy 2.0.31 was released on 2023/02/14. It added 24 new commits
after version 2.0.30.
The main reason for this release today is the availability of a fix for the
vulnerability explained in the other thread (CVE-2023-25725).
In addition, this version addresses the following issues:
- a regression from a previous fix that caused some server-side
connection not to expire if some unsent data are blocked in the
request channel.
- a 13-years old issue with the expiration of old entries in stick-
tables that slows down eviction at every timer period rollover
(49.7 days), making the table size and memory usage grow for a
while until all of them were either refreshed or expired. I'm
still puzzled that 3 users apparently noticed it at the same time
around last rollover on Jan 30th.
- a bug in the SSL cache eviction that affected WolfSSL was fixed, but
it's unclear if it could affect other libs (openssl was apparently not
due to fixed-size records)
- SSL verify error codes above 63 were not properly handled. These
codes changed around OpenSSL 1.1.1 and could exceed this previous
limit, losing some information in error reporting.
- a crash could happen in the H2 mux in 2.2 and earlier when dealing with
an interim response with the end-of-stream flag set.
- a bug in the buffer copy function on wrapping data could theoretically
cause a crash, though we couldn't find instances that could provoke
them. The code has been there for 5 years and this bug might possibly
have caused some such issues but it's too difficult to say, so let's
fix it anyway.
- resolvers incorrectly check expiration dates, that make timeouts
spuriously trigger depending on the position in a ~50-day period.
- the "do_resolv" action did not always yield, waiting for a response,
causing failed resolutions.
- an early failure to start in mworker mode could report a crash if
peers were enabled due to trying to cleanup some parts that were not
completely initialized. It was harmless but particularly confusing for
users.
- the status in logs did not always reflect the one presented to a
users (essentially after an http-after-response rule) but only the
received one. This is finally fixed.
- a warning will be emitted when a crt-list line is malformed.
- minor doc fixes
The changes are intentionally limited so that all users of 2.0.30 and older
can update without taking risks.
