Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process. A miscalculation means an ASN.1 structure used in a Kerberos password change is assumed to be six bytes bigger than it is. This does not affect ordinary packets (the ASN.1 itself contains the correct size), but a crafted ANS1 packet could force up to six unallocated bytes to be read. The usual outcome of this will be a decryption failure and an error message, but it could make the server process crash.
