Vulnerability Note VU#711420

LiveData Server fails to properly handle Connection-Oriented Transport Protocol packets

Original Release date: 02 May 2007 | Last revised: 20 Jul 2007


The LiveData Server fails to handle malformed Connection-Oriented Transport Protocol (COTP) packets. This vulnerability may allow a remote attacker to crash the LiveData Server.


The LiveData Server records and transmits data between two or more control systems. The Connection-Oriented Transport Protocol (COTP) is a transport layer protocol used in OSI networks. COTP is defined in ISO 8073. The LiveData implementation of COTP contains an unspecified vulnerability. By sending a specially crafted packet to a vulnerable LiveData Server, a remote attacker may be able to trigger this vulnerability.


A remote attacker can cause the LiveData Server to terminate abnormally, resulting in a denial-of-service condition.



This vulnerability is remedied in releases 5.00.62 or later of the LiveData Server products. This update is available on the LiveData web site.
