Synopsis

The remote Mandrake Linux host is missing one or more security updates.

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.

Solution

Update the affected packages.
