SECUNIA ADVISORY ID: SA37989

VERIFY ADVISORY: http://secunia.com/advisories/37989/

DESCRIPTION: Some vulnerabilities have been reported in multiple Fujitsu products, which can be exploited by malicious people to bypass certain security restrictions or cause a DoS (Denial of Service).

1) An error when processing client SSL certificates can be exploited to cause a buffer overflow and crash an affected SSL server.

2) An error when processing client or server SSL certificates issued by an old certification authority can be exploited to bypass certain restrictions enforced by an environment variable.

3) An error in the implementation of the SSL server can be exploited to exhaust e.g. available file descriptors.

Please see the vendor’s advisory for a full list of affected products.

SOLUTION: Apply patches. Please see the vendor’s advisory for details.

PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
