Overview
TIBCO Rendezvous and derived components listed above 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.
I. Description
TIBCO has released updates that address critical vulnerabilities in
server and library components of TIBCO Rendezvous.
TIBCO Rendezvous and derived components contain a vulnerability that
may allow an attacker to compromise the server or application by
sending a specially crafted message.
TIBCO strongly recommends sites running the affected components to
install the update or take mitigating action as appropriate.
II. Impact
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, a successful exploit against the Rendezvous
communication daemons (rvd, rvrd, rvsd, rvsrd) will allow arbitrary
code execution with the privileges of the user that invoked that
daemon, with the exception of user id 0 ("root"). If the daemon
component was invoked by user id 0, a successful exploit will
result in access to privileges of user id 65534 ("nobody").
On Unix based systems, a successful exploit against all other
components will allow arbitrary code execution with the privileges
of the user that invoked the server or application.
On Windows based systems, a 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.
III. Solution
Upgrade TIBCO Rendezvous to version 8.1.0 or above. Update all
components derived from TIBCO Rendezvous to use version 8.1.0 or
above. This is strongly recommended.
If an upgrade is not possible, the following actions can mitigate
the vulnerabilities:
* Utilize a firewall to restrict UDP/PGM access to the Rendezvous
network to trusted sources.
* Utilize a firewall to restrict access to the Rendezvous server
port to trusted sources.
* Use a user with restricted privileges to invoke the server
or application.
* On Unix systems, invoke the server or application from a chroot
environment. This will restrict the ability to access or
modify information in the event of a successful exploit.
