Description:
Some vulnerabilities have been reported in TIBCO Rendezvous, which can be exploited by malicious people to conduct DoS (Denial of Service) attacks.
1) An error exists in the TIBCO Rendezvous daemon when processing TIBCO Rendezvous protocol headers. This can be exploited to exhaust system memory by sending a specially crafted packet with a zero length field.
2) An error exists in the processing of messages by the TIBCO Rendezvous daemon. This can be exploited to cause network instability by sending messages to subjects containing lead wildcards (e.g. '>' or '*').
Successful exploitation results in a DoS, but requires that the TIBCO Rendezvous daemon is started without the "-no-lead-wc" option.
The vulnerabilities are reported in version 7.5.2. Other versions may also be affected.
Solution:
Update to version 8.0. Start rvd with "-no-lead-wc".
