Advisory MITKRB5-SA-2007-004 concerns the following vulnerabilities:
CVE-2007-2442:
CVE-2007-2443:
An unauthenticated remote user may be able to cause a host running
kadmind to execute arbitrary code. CVE-2007-2442 is more likely to
lead to arbitrary code execution than CVE-2007-2443.
Successful exploitation can compromise the Kerberos key database and
host security on the host running these programs. (kadmind typically
runs as root.) Unsuccessful exploitation attempts will likely result
in the affected program crashing.
Third-party applications calling the RPC library provided with MIT
krb5 may be vulnerable. Other RPC libraries derived from SunRPC may
be vulnerable.
This vulnerability affects MIT krb5 releases up to and including
krb5-1.6.1. It can affect third-party applications using the RPC
library provided with MIT krb5 releases up to and including
krb5-1.6.1.
