| <background> |
| <p>HAProxy is a TCP/HTTP reverse proxy for high availability environments.</p> |
| </background> |
| <description> |
| <p>A boundary error in HAProxy could cause a buffer overflow when header |
| rewriting is enabled and the configuration sets global.tune.bufsize to a |
| value greater than the default (16384 bytes). |
| </p> |
| </description> |
| <impact type="high"> |
| <p>A remote attacker could possibly execute arbitrary code with the |
| privileges of the process or cause a Denial of Service condition. |
| </p> |
| </impact> |
| <workaround> |
| <p>There is no known workaround at this time.</p> |
| </workaround> |
| <resolution> |
| <p>All HAProxy users should upgrade to the latest version:</p> |

| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-proxy/haproxy-1.4.21" |
