A vulnerability in the Kerberos5 heimdal protocol implementation is related to changing memcmp values for constant
time and a workaround for a compiler error by adding “!= 0” comparisons to the memcmp result.
Exploitation of the vulnerability could allow an attacker acting remotely to perform a logical
inversion, resulting in inverted message integrity code checking in gssapi / arcfour.
