"Updated tomcat6 packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

Apache Tomcat is a servlet container.

It was found that when an application used FORM authentication, along
with another component that calls request.setUserPrincipal() before
the call to FormAuthenticator#authenticate() (such as the
Single-Sign-On valve), it was possible to bypass the security
constraint checks in the FORM authenticator by appending
'/j_security_check' to the end of a URL. A remote attacker with an
authenticated session on an affected application could use this flaw
to circumvent authorization controls, and thereby access resources not
permitted by the roles associated with their authenticated session.
(CVE-2012-3546)

A flaw was found in the way Tomcat handled sendfile operations when
using the HTTP NIO (Non-Blocking I/O) connector and HTTPS. A remote
attacker could use this flaw to cause a denial of service (infinite
loop). The HTTP blocking IO (BIO) connector, which is not vulnerable
to this issue, is used by default in Red Hat Enterprise Linux 6.
(CVE-2012-4534)

Multiple weaknesses were found in the Tomcat DIGEST authentication
implementation, effectively reducing the security normally provided by
DIGEST authentication. A remote attacker could use these flaws to
perform replay attacks in some circumstances. (CVE-2012-5885,
CVE-2012-5886, CVE-2012-5887)

Users of Tomcat should upgrade to these updated packages, which
correct these issues. Tomcat must be restarted for this update to take
effect."

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

Apache Tomcat is a servlet container.

It was found that when an application used FORM authentication, along
with another component that calls request.setUserPrincipal() before
the call to FormAuthenticator#authenticate() (such as the
Single-Sign-On valve), it was possible to bypass the security
constraint checks in the FORM authenticator by appending
'/j_security_check' to the end of a URL. A remote attacker with an
authenticated session on an affected application could use this flaw
to circumvent authorization controls, and thereby access resources not
permitted by the roles associated with their authenticated session.
(CVE-2012-3546)

Multiple weaknesses were found in the Tomcat DIGEST authentication
implementation, effectively reducing the security normally provided by
DIGEST authentication. A remote attacker could use these flaws to
perform replay attacks in some circumstances. (CVE-2012-5885,
CVE-2012-5886, CVE-2012-5887)

Users of Tomcat should upgrade to these updated packages, which
correct these issues. Tomcat must be restarted for this update to take
effect."

A flaw was found in the way Tomcat handled sendfile operations when
using the HTTP NIO (Non-Blocking I/O) connector and HTTPS. A remote
attacker could use this flaw to cause a denial of service (infinite
loop). The HTTP blocking IO (BIO) connector, which is not vulnerable
to this issue, is used by default in Red Hat Enterprise Linux 6.
