Version        : 2.5.1-3+deb11u2
CVE ID         : 
Debian Bug     : 1112516

The upstream fix for CVE-2024-5594 released in DLA-4079-1 restricted characters
in control channel messages including \n and \r, but many scripts add them.
This regression fix basically allows \n and \r in the control channel messages.

For Debian 11 bullseye, this problem has been fixed in version
2.5.1-3+deb11u2.

We recommend that you upgrade your openvpn packages.
