[原文]Buffer overflow in Kerberos IV compatibility libraries as used in Kerberos V allows local users to gain root privileges via a long line in a kerberos configuration file, which can be specified via the KRB_CONF environmental variable.
A local overflow exists in MIT Kerberos 5 when utilizing the Kerberos 4 compatibility libraries. Several Kerberos related programs fail to perform proper boundry checking on the KRB_CONF environment variable. With a specially crafted request, an attacker can gain unauthorized root access to vulnerable systems. This compromise would result in a loss of confidentiality, integrity, and/or availability.
Upgrade to version 1.0.6 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
