Vulnerability Assessment Details

[GLSA-200701-14] Mod_auth_kerb: Denial of Service

Vulnerability Assessment Summary
Mod_auth_kerb: Denial of Service

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200701-14
(Mod_auth_kerb: Denial of Service)

Mod_auth_kerb improperly handles component byte encoding in the
der_get_oid() function, permiting for a buffer overflow to occur if
there are no components which require more than one byte for encoding.

Impact

A possible hacker could try to access a Kerberos protected resource on an
Apache server with an incorrectly configured service principal and
crash the server process. It is important to note that this buffer
overflow is not known to permit for the execution of code.

Workaround

There is no known workaround at this time.
