DESCRIPTION:
Multiple vulnerabilities have been reported in Apache Tomcat, which
can be exploited by malicious, local users to bypass certain security
restrictions and by malicious people to conduct cross-site scripting
attacks and cause a DoS (Denial of Service).

1) An error due to the "ServletContect" attribute improperly being
restricted to read-only when running under a SecurityManager can be
exploited by a malicious web application to use an arbitrary working
directory with read-write privileges.

This vulnerability is reported in versions 5.5.0 through 5.5.29.

2) Certain input (e.g. display names) is not properly sanitised in
the HTML Manager interface before being returned to the user. This
can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site.

This vulnerability is reported in versions 5.5.0 through 5.5.31.

3) An error within the JVM when accessing a page that calls
"javax.servlet.ServletRequest.getLocale()" or
"javax.servlet.ServletRequest.getLocales()" functions can be
exploited to cause the process to hang via a web request containing
specially crafted headers (e.g. "Accept-Language").

This vulnerability is reported in versions prior to 5.5.33.

SOLUTION:
Update to version 5.5.33.

PROVIDED AND/OR DISCOVERED BY:
1, 2) Reported by the vendor.
