CVE ID:	CVE-2010-4020
Description:	MIT Kerberos 5 (aka krb5) 1.8.x through 1.8.3 does not reject RC4 key- derivation checksums, which might allow remote authenticated users to forge a (1) AD-SIGNEDPATH or (2) AD-KDC-ISSUED signature, and possibly gain privileges, by leveraging the small key space that results from certain one-byte stream-cipher operations.
Test IDs:	1.3.6.1.4.1.25623.1.0.68644   1.3.6.1.4.1.25623.1.0.68645   1.3.6.1.4.1.25623.1.0.68692
