The remote Scientific Linux host is missing one or more security
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.
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 Scientific Linux 6.
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,
Tomcat must be restarted for this update to take effect.
