DESCRIPTION:
Some vulnerabilities have been reported in Spring Security, which can
be exploited by malicious people to gain escalated privileges, conduct
HTTP header injection attacks, and bypass certain security
restrictions. 

1) Various errors related to the deserialisation of objects can be
exploited to bypass the authentication mechanism by sending a
specially crafted proxy instance to a vulnerable server.

This is related to vulnerability #1 in:
SA45942

2) A race condition within the RunAsManager implementation can be
exploited to run threads with escalated privileges.

3) Input passed via the redirection parameter
("spring-security-redirect" by default) is not properly sanitised
before being used in a HTTP response. This can be exploited to inject
arbitrary HTML and script code, which is executed in a user's browser
session in context of an affected site.

SOLUTION:
Update to version 2.0.7 or 3.0.6.
