Russ Allbery pam-krb5 before 3.13 as used by libpam-heimdal su in Solaris 10 and other software does not properly handle calls to pam_setcred when running setuid which allows local users to overwrite and change the ownership of arbitrary files by setting the KRB5CCNAME environment variable and then launching a setuid application that performs certain pam_setcred operations.
