An error in the Apache Tomcat JK Connector might allow for an information disclosure flaw.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| www-apache/mod_jk | * | < 1.2.27 | >= 1.2.27 |
The Apache Tomcat JK Connector (aka mod_jk) connects the Tomcat application server with the Apache HTTP Server.
The Red Hat Security Response Team discovered that mod_jk does not properly handle (1) requests setting the "Content-Length" header while not providing data and (2) clients sending repeated requests very quickly.
A remote attacker could send specially crafted requests or a large number of requests at a time, possibly resulting in the disclosure of a response intended for another client.
There is no known workaround at this time.
All Apache Tomcat JK Connector users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-apache/mod_jk-1.2.27"
A directory traversal vulnerability has been discovered in Apache mod_jk.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| www-apache/mod_jk | * | < 1.2.23 | >= 1.2.23 |
Apache mod_jk is a connector for the Tomcat web server.
Apache mod_jk decodes the URL within Apache before passing them to Tomcat, which decodes them a second time.
A remote attacker could browse a specially crafted URL on an Apache server running mod_jk, possibly gaining access to restricted resources.
There is no known workaround at this time.
All Apache mod_jk users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-apache/mod_jk-1.2.23"
The Apache Tomcat Connector (mod_jk) contains a buffer overflow vulnerability that could result in the remote execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| www-apache/mod_jk | * | < 1.2.21-r1 | >= 1.2.21-r1 |
The Apache HTTP server is a very widely used web server. mod_jk provides the JK module for connecting Tomcat and Apache using the ajp13 protocol.
ZDI reported an unsafe memory copy in mod_jk that was discovered by an anonymous researcher in the map_uri_to_worker function of native/common/jk_uri_worker_map.c .
A remote attacker can send a long URL request to an Apache server using Tomcat. That can trigger the vulnerability and lead to a stack-based buffer overflow, which could result in the execution of arbitrary code with the permissions of the Apache user.
There is no known workaround at this time.
All Apache Tomcat users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-apache/mod_jk-1.2.21-r1"
