DESCRIPTION:
A security issue and a vulnerability have been reported in Apache
Tomcat, which can be exploited by malicious, local users to bypass
certain security restrictions or cause a DoS (Denial of Service).

1) The security issue is caused due to Apache Tomcat not properly
verifying sendfile request attributes when running under a security
manager, which can be exploited by a malicious web application to
bypass intended restrictions and e.g. disclose local files.

2) The vulnerability is caused due to Apache Tomcat not properly
handling sendfile request with invalid start and endpoints, which can
be exploited to crash the JVM.

Successful exploitation requires that a malicious web application is
deployed and a security manager and the HTTP NIO or HTTP APR
connector with enabled sendfile is used.

SOLUTION:
Update to versions 5.5.34, 6.0.33, or 7.0.19 when available. Also
fixed in the SVN repository and the vendor has also provided a
proposed patch for Apache Tomcat versions 5 and 6.
