+Subject: [PATCH] Fix CVE-2022-43995, potential heap overflow for passwords < 8
+ characters. Starting with sudo 1.8.0 the plaintext password buffer is
+ dynamically sized so it is not safe to assume that it is at least 9 bytes in
+ size. Found by Hugo Lefeuvre (University of Manchester) with ConfFuzz.
