Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities in Apache might lead to a Denial of Service. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
The Apache HTTP server is one of the most popular web servers on the |
| 24 |
Internet. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |

|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Multiple vulnerabilities have been discovered in Apache: |
| 38 |
|
| 39 |
* Dustin Kirkland reported that the mod_ssl module can leak memory |
| 40 |
when the client reports support for a compression algorithm |
| 41 |
(CVE-2008-1678). |
| 42 |
|
| 43 |
* Ryujiro Shibuya reported that the ap_proxy_http_process_response() |
| 44 |
function in the mod_proxy module does not limit the number of |
| 45 |
forwarded interim responses (CVE-2008-2364). |
| 46 |
|
| 47 |
* sp3x of SecurityReason reported a Cross-Site Request Forgery |
| 48 |
vulnerability in the balancer-manager in the mod_proxy_balancer |
| 49 |
module (CVE-2007-6420). |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
A remote attacker could exploit these vulnerabilities by connecting to |
| 55 |
an Apache httpd, by causing an Apache proxy server to connect to a |
| 56 |
malicious server, or by enticing a balancer administrator to connect to |
| 57 |
a specially-crafted URL, resulting in a Denial of Service of the Apache |
| 58 |
daemon. |
| 59 |
|
| 60 |
Workaround |
| 61 |
========== |
| 62 |
|
| 63 |
There is no known workaround at this time. |
| 64 |
|
| 65 |
Resolution |
| 66 |
========== |
| 67 |
|
| 68 |
All Apache users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=www-servers/apache-2.2.9" |
| 72 |
|
