Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2011:0791
The remote host is missing updates announced in
advisory RHSA-2011:0791.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer
Pages (JSP) technologies.

It was found that web applications could modify the location of the Tomcat
host's work directory. As web applications deployed on Tomcat have read and
write access to this directory, a malicious web application could use this
flaw to trick Tomcat into giving it read and write access to an arbitrary
directory on the file system. (CVE-2010-3718)

A cross-site scripting (XSS) flaw was found in the Manager application,
used for managing web applications on Tomcat. If a remote attacker could
trick a user who is logged into the Manager application into visiting a
specially-crafted URL, the attacker could perform Manager application tasks
with the privileges of the logged in user. (CVE-2010-4172)

A second cross-site scripting (XSS) flaw was found in the Manager
application. A malicious web application could use this flaw to conduct an
XSS attack, leading to arbitrary web script execution with the privileges
of victims who are logged into and viewing Manager application web pages.

This update also fixes the following bugs:

* A bug in the tomcat6 init script prevented additional Tomcat instances
from starting. As well, running service tomcat6 start caused
configuration options applied from /etc/sysconfig/tomcat6 to be
overwritten with those from /etc/tomcat6/tomcat6.conf. With this update,
multiple instances of Tomcat run as expected. (BZ#636997)

* The /usr/share/java/ directory was missing a symbolic link to the
/usr/share/tomcat6/bin/tomcat-juli.jar library. Because this library was
mandatory for certain operations (such as running the Jasper JSP
precompiler), the build-jar-repository command was unable to compose a
valid classpath. With this update, the missing symbolic link has been
added. (BZ#661244)

* Previously, the tomcat6 init script failed to start Tomcat with a This
account is currently not available. message when Tomcat was configured to
run under a user that did not have a valid shell configured as a login
shell. This update modifies the init script to work correctly regardless of
the daemon user's login shell. Additionally, these new tomcat6 packages now
set /sbin/nologin as the login shell for the tomcat user upon
installation, as recommended by deployment best practices. (BZ#678671)

* Some standard Tomcat directories were missing write permissions for the
tomcat group, which could cause certain applications to fail with errors
such as No output folder. This update adds write permissions for the
tomcat group to the affected directories. (BZ#643809)

* The /usr/sbin/tomcat6 wrapper script used a hard-coded path to the
catalina.out file, which may have caused problems (such as for logging
init script output) if Tomcat was being run with a user other than tomcat
and with CATALINA_BASE set to a directory other than the default.
(BZ#695284, BZ#697504)

* Stopping Tomcat could have resulted in traceback errors being logged to
catalina.out when certain web applications were deployed. (BZ#698624)

Users of Tomcat should upgrade to these updated packages, which contain
backported patches to correct these issues. Tomcat must be restarted for
this update to take effect.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
