Scientific Linux Security Update : tomcat6 on SL6.x (noarch) (httpoxy)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

Security Fix(es) :

- It was discovered that the Tomcat packages installed
certain configuration files read by the Tomcat
initialization script as writeable to the tomcat group.
A member of the group or a malicious web application
deployed on Tomcat could use this flaw to escalate their
privileges. (CVE-2016-6325)

- It was found that several Tomcat session persistence
mechanisms could allow a remote, authenticated user to
bypass intended SecurityManager restrictions and execute
arbitrary code in a privileged context via a web
application that placed a crafted object in a session.
(CVE-2016-0714)

- It was discovered that tomcat used the value of the
Proxy header from HTTP requests to initialize the
HTTP_PROXY environment variable for CGI scripts, which
in turn was incorrectly used by certain HTTP client
implementations to configure the proxy for outgoing HTTP
requests. A remote attacker could possibly use this flaw
to redirect HTTP requests performed by a CGI script to
an attacker-controlled proxy via a malicious HTTP
request. (CVE-2016-5388)

- A directory traversal flaw was found in Tomcat's
RequestUtil.java. A remote, authenticated user could use
this flaw to bypass intended SecurityManager
restrictions and list a parent directory via a '/..' in
a pathname used by a web application in a getResource,
getResourceAsStream, or getResourcePaths call, as
demonstrated by the $CATALINA_BASE/webapps directory.
(CVE-2015-5174)

- It was found that Tomcat could reveal the presence of a
directory even when that directory was protected by a
security constraint. A user could make a request to a
directory via a URL not ending with a slash and,
depending on whether Tomcat redirected that request,
could confirm whether that directory existed.
(CVE-2015-5345)

- It was found that Tomcat allowed the
StatusManagerServlet to be loaded by a web application
when a security manager was configured. This allowed a
web application to list all deployed web applications
and expose sensitive information such as session IDs.
(CVE-2016-0706)

Bug Fix(es) :

- Due to a bug in the tomcat6 spec file, the catalina.out
file's md5sum, size, and mtime attributes were compared
to the file's attributes at installation time. Because
these attributes change after the service is started,
the 'rpm -V' command previously failed. With this
update, the attributes mentioned above are ignored in
the RPM verification and the catalina.out file now
passes the verification check.
