Dist Debian Esm H88
Numerous critical memory vulnerabilities in OpenVPN on Debian 7 have been addressed in the recent security patch to enhance safety.
It was discovered that there were multiple out-of-bounds memory read vulnerabilities in openvpn, a popular virtual private network (VPN) daemon

Summary

If clients used a HTTP proxy with NTLM authentication, a man-in-the-middle
attacker could cause the client to crash or disclose at most 96 bytes of stack
memory, likely to contain the proxy password.

For Debian 7 "Wheezy", this issue has been fixed in openvpn version
2.2.1-8+deb7u5.

We recommend that you upgrade your openvpn packages.
