Detail
| Tom Yu and Sam Hartman of MIT discovered another stack buffer overflow in the kadm_ser_wrap_in function in the Kerberos v4 administration server. This kadmind bug has a working exploit code circulating, hence it is considered serious. The MIT krb5 implementation includes support for version 4, including a complete v4 library, server side support for krb4, and limited client support for v4. This problem has been fixed in version 1.2.4-5woody3 for the current stable distribution (woody) and in version 1.2.6-2 for the unstable distribution (sid). The old stable distribution (potato) is not affected since no krb5 packages are included. We recommend that you upgrade your krb5 packages immediately. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.

| Id | Description |
|---|---|
| 5618 | Heimdal Kerberos kf / kfd Multiple Buffer Overflows Multiple remote overflows exist in Heimdal Kerberos. The 'kf' binary and the 'kfd' daemon fail to perform proper bounds checking resulting in multiple buffer overflows. With a specially crafted request, a remote attacker can cause arbitrary code execution resulting in a loss of integrity. |
| 4900 | Heimdal Kerberos kadmind Forwarding Daemon Overflow Heimdal Kerberos contains a flaw that may allow a malicious user to exploit a buffer overflow condition. The issue is triggered because Heimdal does not properly verify the length field of a request to the Kerberos forwarding daemon. It is possible that the flaw may allow remote attackers to execute arbitrary code resulting in a loss of confidentiality, integrity, and/or availability. |
| 4870 | Multiple Kerberos Compatibility Administration Daemon Overflow A remote overflow exists in several implementations of Kerberos 4 and legacy compatibility for Kerberos 4 in kerberos 5 distributions. The kadmind daemon fails to do proper bounds checking, resulting in a stack overflow. With a specially crafted request, an attacker can cause the daemon to execute arbitrary commands on the server, resulting in a loss of integrity. |
