Title:	OpenSSL 'kssl_keytab_is_available()' DoS Vulnerability - Windows
Summary:	OpenSSL is prone to a denial of service (DoS) vulnerability.
Description:	Summary: OpenSSL is prone to a denial of service (DoS) vulnerability. Vulnerability Insight: The flaw is due to error in 'kssl_keytab_is_available()' function in 'ssl/kssl.c' which does not check a certain return value when Kerberos is enabled. This allows NULL pointer dereference and daemon crash via SSL cipher negotiation. Vulnerability Impact: Successful exploitation will allow an attacker to cause DoS conditions. Affected Software/OS: OpenSSL version prior to 0.9.8n. Solution: Update to version 0.9.8n or later. CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
