Test ID:1.3.6.1.4.1.25623.1.0.58199
Category:Turbolinux Local Security Tests
Title:Turbolinux TLSA-2007-24 (krb5)
Summary:NOSUMMARY
Description:Description:

The remote host is missing an update to krb5
announced via advisory TLSA-2007-24.

Kerberos V5 is a trusted-third-party network authentication system,
which can improve your network's security by eliminating the insecure
practice of cleartext passwords.

- The MIT krb5 telnet daemon (krb5-telnet) allows unauthorized login as an
arbitrary user, when presented with a specially crafted username.
Exploitation of this vulnerability is trivial.
- The library function krb5_klog_syslog() can write past the end of a
stack buffer. The Kerberos administration daemon (kadmind) as well as
the KDC, are vulnerable. Exploitation of this vulnerability is probably simple.
- The GSS-API library provided with MIT krb5 contains a vulnerability that may
allow a remote, authenticated attacker to execute arbitrary code or
cause a denial of service.

A user can gain unauthorized access to any account (including root) on
a host running telnetd.
The krb5 allows remote attackers to cause a host running kadmind to
execute arbitrary code.
The krb5 allows remote attackers to cause a denial of service.

Solution: Please use the turbopkg (zabom) tool to apply the update.
