PACKAGE : heimdal
SUMMARY : protocol bug in the kerberos v4 cross-realm operation
DATE : 2003-05-27 08:46 UTC
EXPLOIT : remote
VERSIONS AFFECTED : <heimdal-0.6
FIXED VERSION : >=heimdal-0.6
CVE : CAN-2003-0139 CAN-2003-0138

heimdal suffers from the same vulnerability as mit-krb5 does, hence
the identical advisory.

- - From advisory:
"A cryptographic weakness in version 4 of the Kerberos protocol allows
an attacker to use a chosen-plaintext attack to impersonate any
principal in a realm. Additional cryptographic weaknesses in the krb4
implementation included in the MIT krb5 distribution permit the use of
cut-and-paste attacks to fabricate krb4 tickets for unauthorized
client principals if triple-DES keys are used to key krb4 services.
These attacks can subvert a site's entire Kerberos authentication

Read the full advisory at


It is recommended that all Gentoo Linux users who are running
app-crypt/heimdal upgrade to heimdal-0.6 as follows

emerge sync
emerge heimdal
emerge clean
