DaoAuthenticationProvider in VMware SpringSource Spring Security before 2.0.8, 3.0.x before 3.0.8, and 3.1.x before 3.1.3 does not check the password if the user is not found, which makes the response delay shorter and might allow remote attackers to enumerate valid usernames via a series of login requests.

CRLF injection vulnerability in the logout functionality in VMware SpringSource Spring Security before 2.0.7 and 3.0.x before 3.0.6 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via the spring-security-redirect parameter.

Race condition in the RunAsManager mechanism in VMware SpringSource Spring Security before 2.0.7 and 3.0.x before 3.0.6 stores the Authentication object in the shared security context, which allows attackers to gain privileges via a crafted thread.

VMware SpringSource Spring Security 2.x before 2.0.6 and 3.x before 3.0.4, and Acegi Security 1.0.0 through 1.0.7, as used in IBM WebSphere Application Server (WAS) 6.1 and 7.0, allows remote attackers to bypass security constraints via a path parameter.
