 Mandriva Linux Security Advisory                       MDKSA-2007:077-1
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : krb5
 Date    : April 10, 2007
 Affected: 2007.1
 _______________________________________________________________________
 
 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.

 Update:

 Packages for Mandriva Linux 2007.1 are now available.
