| <background> |
| <p> |
| lighttpd is a small-footprint, fast, compliant and very flexible |
| web-server which is optimized for high-performance environments. |

| <description> |
| <p> |
| lighttpd uses file extensions to determine which elements are programs |
| that should be executed and which are static pages that should be sent |
| as-is. By appending %00 to the filename, you can evade the extension |
| detection mechanism while still accessing the file. |
| </p> |
| </description> |
| <impact type="low"> |
| <p> |
| A remote attacker could send specific queries and access the source of |
| scripts that should have been executed as CGI or FastCGI applications. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |

| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.3.10-r1"</code> |
