Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
The Apache Tomcat Connector (mod_jk) contains a buffer overflow |
| 20 |
vulnerability that could result in the remote execution of arbitrary |
| 21 |
code. |
| 22 |
|
| 23 |
Background |
| 24 |
========== |
| 25 |
|
| 26 |
The Apache HTTP server is a very widely used web server. mod_jk |
| 27 |
provides the JK module for connecting Tomcat and Apache using the ajp13 |
| 28 |
protocol. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|
| 33 |
------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |
------------------------------------------------------------------- |
| 36 |
1 www-apache/mod_jk < 1.2.21-r1 >= 1.2.21-r1 |

Description |
| 39 |
=========== |
| 40 |
|
| 41 |
ZDI reported an unsafe memory copy in mod_jk that was discovered by an |
| 42 |
anonymous researcher in the map_uri_to_worker function of |
| 43 |
native/common/jk_uri_worker_map.c . |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
A remote attacker can send a long URL request to an Apache server using |
| 49 |
Tomcat. That can trigger the vulnerability and lead to a stack-based |
| 50 |
buffer overflow, which could result in the execution of arbitrary code |
| 51 |
with the permissions of the Apache user. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All Apache Tomcat users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge --sync |
| 64 |
# emerge --ask --oneshot --verbose ">=www-apache/mod_jk-1.2.21-r1" |
| 65 |
|
