-Subject: [PATCH] Fix double-free in KDC TGS processing
-
-When issuing a ticket for a TGS renew or validate request, copy only
-the server field from the outer part of the header ticket to the new
-ticket.  Copying the whole structure causes the enc_part pointer to be
-aliased to the header ticket until krb5_encrypt_tkt_part() is called,
-resulting in a double-free if handle_authdata() fails.
-
-[ghudson@mit.edu: changed the fix to avoid aliasing enc_part rather
-than check for aliasing before freeing; rewrote commit message]
-
-CVE-2023-39975:
-
-In MIT krb5 release 1.21, an authenticated attacker can cause a KDC to
-free the same pointer twice if it can induce a failure in
-authorization data handling.
