(RHSA-2007:0871) Moderate: tomcat security update

Tomcat is a servlet container for Java Servlet and Java Server Pages
technologies.

Tomcat was found treating single quote characters – ’ – as delimiters in
cookies. This could allow remote attackers to obtain sensitive information,
such as session IDs, for session hijacking attacks (CVE-2007-3382).

It was reported Tomcat did not properly handle the following character
sequence in a cookie: " (a backslash followed by a double-quote). It was
possible remote attackers could use this failure to obtain sensitive
information, such as session IDs, for session hijacking attacks
(CVE-2007-3385).

A cross-site scripting (XSS) vulnerability existed in the Host Manager
Servlet. This allowed remote attackers to inject arbitrary HTML and web
script via crafted requests (CVE-2007-3386).

Users of Tomcat should update to these erratum packages, which contain
backported patches and are not vulnerable to these issues.
