NVD-CWE-noinfoPublished: December 6, 2007· Updated: Jun 16, 2026
Official Description
The reply function in ftpd.c in the gssftp ftpd in MIT Kerberos 5 (krb5) does not initialize the length variable when auth_type has a certain value, which has unknown impact and remote authenticated attack vectors. NOTE: the original disclosure misidentifies the conditions under which the uninitialized variable is used. NOTE: the vendor disputes this issue, stating " The 'length' variable is only uninitialized if 'auth_type' is neither the 'KERBEROS_V4' nor 'GSSAPI'; this condition cannot occur in the unmodified source code.
Technical Analysis
CVE-2007-5894 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
