A format string vulnerability + in the foreign_option function in options.c could + potentially allow a malicious or compromised server + to execute arbitrary code on the client. Only + non-Windows clients are affected. The vulnerability + only exists if (a) the client's TLS negotiation with + the server succeeds, (b) the server is malicious or + has been compromised such that it is configured to + push a maliciously crafted options string to the client, + and (c) the client indicates its willingness to accept + pushed options from the server by having "pull" or + "client" in its configuration file. +* Security fix -- Potential DoS vulnerability on the + server in TCP mode. If the TCP server accept() call + returns an error status, the resulting exception handler + may attempt to indirect through a NULL pointer, causing + a segfault. Affects all OpenVPN 2.0 versions. * Fix attempt of assertion at multi.c:1586 (note that this precise line number will vary across different versions of OpenVPN). |
