Detail
| A stack buffer overflow in the kadm_ser_wrap_in function in the Kerberos v4 administration server was discovered, which is provided by Heimdal as well. A working exploit for this kadmind bug is already circulating, hence it is considered serious. The roken library also contains a vulnerability which could lead to another root exploit. These problems have been fixed in version 0.4e-7.woody.5 for the current stable distribution (woody), in version 0.2l-7.6 for the old stable distribution (potato) and in version 0.4e-22 for the unstable distribution (sid). We recommend that you upgrade your heimdal 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.

Open Source Vulnerability Database (OSVDB)
| 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. |
