Synopsis

Moderate: tomcat security update for Red Hat Network Satellite Server

Type/Severity

Security Advisory: Moderate

Topic

Updated tomcat packages that fix multiple security issues are now available
for Red Hat Network Satellite Server.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

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

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).

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).

The default Tomcat configuration permitted the use of insecure
SSL cipher suites including the anonymous cipher suite. (CVE-2007-1858)

Tomcat permitted various characters as path delimiters. If Tomcat was used
behind certain proxies and configured to only proxy some contexts, an
attacker could construct an HTTP request to work around the context
restriction and potentially access non-proxied content. (CVE-2007-0450)

Directory listings were enabled by default in Tomcat. Information stored
unprotected under the document root was visible to anyone if the
administrator did not disable directory listings. (CVE-2006-3835)

It was found that generating listings of large directories was CPU
intensive. An attacker could make repeated requests to obtain a directory
listing of any large directory, leading to a denial of service.
(CVE-2005-3510)

Tomcat was found to accept multiple content-length headers in a
request. This could allow attackers to poison a web-cache, bypass web
application firewall protection, or conduct cross-site scripting attacks.
(CVE-2005-2090)

Users should upgrade to these erratum packages which contain an update to
Tomcat that resolves these issues, and add the tyrex and
jakarta-commons-pool packages which are required dependencies of the new
Tomcat version.
