-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : krb5 SUMMARY : Fix for buffer overflow in libkadm5srv DATE : 2005-01-13 11:56:00 ID : CLA-2005:917 RELEVANT RELEASES : 9, 10 - ------------------------------------------------------------------------- DESCRIPTION The "krb5" packages are MIT's[1] implementation of the Kerberos 5 authentication protocol. Michael Tautschnig noticed that the MIT Kerberos 5 administration library (libkadm5srv) contains a heap buffer overflow[2] in password history handling code which could be exploited by an authenticated user to execute arbitrary code on a Key Distribution Center (KDC) host. For further information about this vulnerability, please refer to MIT krb5 Security Advisory 2004-004[3]. SOLUTION It is recommended that all Kerberos users in Conectiva Linux upgrade their packages. Please note that the service will be automatically restarted after the upgrade if it was already running. Several applications can make use of the Kerberos libraries. Those applications have to be restarted as well.
