Debian DLA-999-1 : openvpn security update

high Nessus Plugin ID 101007

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there were multiple out-of-bounds memory read vulnerabilities in openvpn, a popular virtual private network (VPN) daemon.

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected openvpn package.
