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 directory traversal vulnerability existed in the Apache Tomcat webdav servlet. This allowed remote attackers to remote authenticated users to read accessible to the local user running the tomcat process (CVE-2007-5461).
The default security policy in the JULI logging component did not restrict access permissions to files. This could be misused by untrusted web applications to access and write arbitrary files in the context of the tomcat process (CVE-2007-5342).
Users of Tomcat should update to these erratum packages, which contain backported patches and are not vulnerable to these issues.
