|Bugzilla:||947581: CVE-2013-1912 haproxy: rewrite rules flaw can lead to arbitrary code execution|
The MITRE CVE dictionary describes this issue as:
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.
