Details
USN-511-1 fixed vulnerabilities in krb5 and librpcsecgss. The fixes were
incomplete, and only reduced the scope of the vulnerability, without fully
solving it. This update fixes the problem.
Original advisory details:
It was discovered that the libraries handling RPCSEC_GSS did not correctly
validate the size of certain packet structures. An unauthenticated remote
user could send a specially crafted request and execute arbitrary code
with root privileges.
