Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Apache can be exploited for cross-site scripting attacks and is |
| 19 |
vulnerable to a Denial of Service attack. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The Apache HTTP server is one of the most popular web servers on the |
| 25 |
Internet. mod_imap provides support for server-side image maps; mod_ssl |
| 26 |
provides secure HTTP connections. |
| 27 |
|
| 28 |
Affected packages |

Description |
| 40 |
=========== |
| 41 |
|
| 42 |
Apache's mod_imap fails to properly sanitize the "Referer" directive of |
| 43 |
imagemaps in some cases, leaving the HTTP Referer header unescaped. A |
| 44 |
flaw in mod_ssl can lead to a NULL pointer dereference if the site uses |
| 45 |
a custom "Error 400" document. These vulnerabilities were reported by |
| 46 |
Marc Cox and Hartmut Keil, respectively. |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
A remote attacker could exploit mod_imap to inject arbitrary HTML or |
| 52 |
JavaScript into a user's browser to gather sensitive information. |
| 53 |
Attackers could also cause a Denial of Service on hosts using the SSL |
| 54 |
module (Apache 2.0.x only). |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There is no known workaround at this time. |
| 60 |
|
| 61 |
Resolution |
| 62 |
========== |
| 63 |
|
| 64 |
All Apache users should upgrade to the latest version, depending on |
| 65 |
whether they still use the old configuration style |
| 66 |
(/etc/apache/conf/*.conf) or the new one (/etc/apache2/httpd.conf). |
| 67 |
|
| 68 |
2.0.x users, new style config: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=net-www/apache-2.0.55-r1" |
| 72 |
|
| 73 |
2.0.x users, old style config: |
| 74 |
|
| 75 |
# emerge --sync |
| 76 |
# emerge --ask --oneshot --verbose "=net-www/apache-2.0.54-r16" |
| 77 |
|
| 78 |
1.x users, new style config: |
| 79 |
|
| 80 |
# emerge --sync |
| 81 |
# emerge --ask --oneshot --verbose "=net-www/apache-1.3.34-r11" |
| 82 |
|
| 83 |
1.x users, old style config: |
| 84 |
|
| 85 |
# emerge --sync |
| 86 |
# emerge --ask --oneshot --verbose "=net-www/apache-1.3.34-r2" |
| 87 |
