Package name krb5
Date April 4th, 2007
Advisory ID MDKSA-2007:077
Affected versions CS3.0, MNF2.0, 2006.0, 2007.0, CS4.0
Synopsis Updated krb5 packages fix vulnerabilities

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.
