CVE-2015-3281 (CCN-104549)

Assigned:2015-07-06
Published:2015-07-06
Updated:2023-02-13
Summary: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.
