+Subject: [PATCH] Fix potential DoS issue with p2c header
+
+Unbounded p2c headers may be used to cause an application that accept
+PBES algorithms to spend alot of resources running PBKDF2 with a very
+high number of iterations.
+
+Clamp the default maximum to 16384 (double the default of 8192).
+An application that wants to use more iterations will have to chenge the
+jwa default max.
+
+Fixes CVE-2023-6681
