Description

Buffer overflow in HAProxy 1.4 through 1.4.22 and 1.5-dev through 1.5-dev17 when HTTP keep-alive is enabled using HTTP keywords in TCP inspection rules and running with rewrite rules that appends to requests allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted pipelined HTTP requests that prevent request realignment from occurring.
