Description:
Hendrik Weimer has reported a vulnerability in OpenVPN, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to OpenVPN clients allowing the server to transmit environment variables including LD_PRELOAD to client-side shell scripts via "setenv" configuration directives. This can be exploited to execute arbitrary code on a vulnerable client by placing a malicious file in a known location and load this.
Successful exploitation requires that a user connects to a malicious server.
The vulnerability has been reported in versions 2.0 through 2.0.5.
