+Subject: [PATCH] CVE-2022-43995
+
+Upstream-Status: Backport [https://github.com/sudo-project/sudo/commit/bd209b9f16fcd1270c13db27ae3329c677d48050]
+CVE: CVE-2022-43995
+Signed-off-by: Hitendra Prajapati <hprajapati@mvista.com>
+
+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.
