Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities in lighttpd may lead to information disclosure |
| 19 |
or a Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
lighttpd is a lightweight high-performance web server. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Multiple vulnerabilities have been reported in lighttpd: |
| 38 |
|
| 39 |
* Qhy reported a memory leak in the http_request_parse() function in |
| 40 |
request.c (CVE-2008-4298). |
| 41 |
|
| 42 |
* Gaetan Bisson reported that URIs are not decoded before applying |
| 43 |
url.redirect and url.rewrite rules (CVE-2008-4359). |
| 44 |
|
| 45 |
* Anders1 reported that mod_userdir performs case-sensitive |
| 46 |
comparisons on filename components in configuration options, which is |
| 47 |
insufficient when case-insensitive filesystems are used |
| 48 |
(CVE-2008-4360). |
| 49 |
|
| 50 |
Impact |
| 51 |
====== |
| 52 |
|
| 53 |
A remote attacker could exploit these vulnerabilities to cause a Denial |
| 54 |
of Service, to bypass intended access restrictions, to obtain sensitive |
| 55 |
information, or to possibly modify data. |
| 56 |
|
| 57 |
Workaround |
| 58 |
========== |
| 59 |
|
| 60 |
There is no known workaround at this time. |
| 61 |
|
| 62 |
Resolution |
| 63 |
========== |
| 64 |
|
| 65 |
All lighttpd users should upgrade to the latest version: |
| 66 |
|
| 67 |
# emerge --sync |
| 68 |
# emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.20" |
| 69 |
