Multiple vulnerabilities has been found and corrected in tomcat5:

Apache Tomcat 6.0.0 through 6.0.14, 5.5.0 through 5.5.25, and 4.1.0
through 4.1.36 does not properly handle (1) double quote (") characters
or (2) %5C (encoded backslash) sequences in a cookie value, which
might cause sensitive information such as session IDs to be leaked
to remote attackers and enable session hijacking attacks. NOTE:
this issue exists because of an incomplete fix for CVE-2007-3385
(CVE-2007-5333).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, 6.0.0 through
6.0.18, and possibly earlier versions normalizes the target pathname
before filtering the query string when using the RequestDispatcher
method, which allows remote attackers to bypass intended access
restrictions and conduct directory traversal attacks via .. (dot dot)
sequences and the WEB-INF directory in a Request (CVE-2008-5515).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0
through 6.0.18, when the Java AJP connector and mod_jk load balancing
are used, allows remote attackers to cause a denial of service
(application outage) via a crafted request with invalid headers,
related to temporary blocking of connectors that have encountered
errors, as demonstrated by an error involving a malformed HTTP Host
header (CVE-2009-0033).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and
6.0.0 through 6.0.18, when FORM authentication is used, allows
remote attackers to enumerate valid usernames via requests to
/j_security_check with malformed URL encoding of passwords, related to
improper error checking in the (1) MemoryRealm, (2) DataSourceRealm,
and (3) JDBCRealm authentication realms, as demonstrated by a %
(percent) value for the j_password parameter (CVE-2009-0580).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0
through 6.0.18 permits web applications to replace an XML parser used
for other web applications, which allows local users to read or modify
the (1) web.xml, (2) context.xml, or (3) tld files of arbitrary web
applications via a crafted application that is loaded earlier than
the target application (CVE-2009-0783).

Directory traversal vulnerability in Apache Tomcat 5.5.0 through
5.5.28 and 6.0.0 through 6.0.20 allows remote attackers to create or
overwrite arbitrary files via a .. (dot dot) in an entry in a WAR file,
as demonstrated by a ../../bin/catalina.bat entry (CVE-2009-2693).

The autodeployment process in Apache Tomcat 5.5.0 through 5.5.28 and
6.0.0 through 6.0.20, when autoDeploy is enabled, deploys appBase
files that remain from a failed undeploy, which might allow remote
attackers to bypass intended authentication requirements via HTTP
requests (CVE-2009-2901).

Directory traversal vulnerability in Apache Tomcat 5.5.0 through
5.5.28 and 6.0.0 through 6.0.20 allows remote attackers to delete
work-directory files via directory traversal sequences in a WAR
filename, as demonstrated by the ...war filename (CVE-2009-2902).

Apache Tomcat 5.5.0 through 5.5.29 and 6.0.0 through 6.0.26 might
allow remote attackers to discover the server's hostname or IP
address by sending a request for a resource that requires (1) BASIC or
(2) DIGEST authentication, and then reading the realm field in the
WWW-Authenticate header in the reply (CVE-2010-1157).

Apache Tomcat 5.5.0 through 5.5.29, 6.0.0 through 6.0.27, and 7.0.0
beta does not properly handle an invalid Transfer-Encoding header,
which allows remote attackers to cause a denial of service (application
outage) or obtain sensitive information via a crafted header that
interferes with recycling of a buffer. (CVE-2010-2227)
