TIBCO SmartSockets components listed below contain buffer overflow vulnerabilities in the processing of inbound data. The impact of these vulnerabilities may include remote execution of arbitrary code, information disclosure, and denial of service.
TIBCO has released updates which address critical vulnerabilities in the server and library components of the TIBCO SmartSockets.
These vulnerabilities directly affect the SmartSockets server (rtserver) and applications utilizing the TipcConnAccept interface. These vulnerabilities may also affect applications utilizing the SmartSockets libraries if an attacker is able to inject data into the server/client TCP connection.
TIBCO strongly recommends sites running the affected components to install the update or take mitigating action as appropriate.
The following components are affected:
The impact of these vulnerabilities varies depending on the operating system and the privilege levels of the user that invokes the server or application.
On Unix based systems, the successful exploit will allow arbitrary code execution with the privileges of the user that invoked the server or application.
On Windows based systems, the successful exploit will allow arbitrary code execution with the privileges of the user that invoked the server or application. If the server or application is installed as a system service, this will result in access to system privileges.
Upgrade TIBCO SmartSockets to version 6.8.1 or above. This is strongly recommended.
If an upgrade is not possible, the following actions can mitigate the vulnerabilities:
