Hello,

An out-of-bounds read has been found [1] in OpenVPN < 2.3.9, and fixed in 2.3.9. This is not clear whether it's actually exploitable, I will update this issue as soon as I know more.

2.3.9 is in testing.

Note: I removed the systemd askpass patch because it does not merge. The commit 62ba55a claims to fix it properly.
