Mandriva Linux Security Advisory MDKSA-2007:077
http://www.mandriva.com/security/
_______________________________________________________________________

Package : krb5
Date : April 4, 2007
Affected: 2006.0, 2007.0, Corporate 3.0, Corporate 4.0,
Multi Network Firewall 2.0
_______________________________________________________________________

Problem Description:

A vulnerability was found in the username handling of the MIT krb5
telnet daemon. A remote attacker that could access the telnet port
of a target machine could login as root without requiring a password
(CVE-2007-0956).

Buffer overflows in the kadmin server daemon were discovered that could
be exploited by a remote attacker able to access the KDC. Successful
exploitation could allow for the execution of arbitrary code with the
privileges of the KDC or kadmin server processes (CVE-2007-0957).

Finally, a double-free flaw was discovered in the GSSAPI library used
by the kadmin server daemon, which could lead to a denial of service
condition or the execution of arbitrary code with the privileges of
the KDC or kadmin server processes (CVE-2007-1216).

Updated packages have been patched to address this issue.
