CVE-2015-3281 - Mistaken Calibrations

Description

The buffer_slow_realign function in HAProxy 1.5.x before 1.5.14 and 1.6-dev does not properly realign a buffer that is used for pending outgoing data which allows remote attackers to obtain sensitive information (uninitialized memory contents of previous requests) via a crafted request.
