Multiple vulnerabilities have been identified in BEA WebLogic Server, which could be exploited by attackers to bypass security restrictions, disclose sensitive information or cause a denial of service.
The first issue is caused by an unspecified error which could cause SSL clients that run outside the server environment to not find all possible ciphers, resulting in use of the default null cipher (no encryption).
The second vulnerability is caused by an error when communicating with a client that does not offer support for any of the cipher suites available in the server, which could cause the server to select a cipher suite that uses a null cipher (no encryption).
The third issue is caused by an error when processing data sent from clients, which could be exploited by attackers to crash an affected server, leading to a denial of service.
The fourth vulnerability is caused by an error when processing malformed headers, which could cause the server log to utilize significant disk space and potentially the entire disk, leading to a denial of service.
