Advisory: https://www.mail-archive.com/haproxy@formilux.org/msg43229.html

"""
A team of security researchers notified me on Thursday evening that they
had found a dirty bug in HAProxy's headers processing, and that, when
properly exploited, this bug allows to build an HTTP content smuggling
attack. HTTP content smuggling attacks consist in passing extra requests
after a first one on a connection to a proxy, and making the subsequent
ones bypass the filtering in place.

[...]

Please stable the fixed versions, thanks!
