| Descripción: | Summary:
The remote host is missing an update for the 'tomcat6'
package(s) announced via the referenced advisory.
Vulnerability Insight:
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.
(CVE-2011-0013)
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 ...
