Vulnerability Note VU#561275
OpenSSL servers contain a remotely exploitable buffer overflow vulnerability during the SSL3 handshake process
OpenSSL is an open-source implementation of the Secure Sockets Layer (SSL) protocol. A remotely exploitable vulnerability exists in OpenSSL servers that could lead to the execution of arbitrary code on the system
Servers running OpenSSL pre-release version 0.9.7 with Kerberos enabled, contain a remotely exploitable buffer overflow vulnerability. This vulnerability can be exploited by a malicious client sending a malformed key during the SSLv3 handshake process with the server.
A remote attacker may be able to execute arbitrary code on the server with the privileges of the exploited application or service.
OpenSSL Clients should apply the patches provided by your vendors, or upgrade to OpenSSL 0.9.6e. Note that applications statically linking to OpenSSL libraries may need to be recompiled with the corrected version of OpenSSL.
