Description:
Michael Tautschnig has reported a vulnerability in Kerberos V5, which potentially can be exploited by malicious users to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the libkadm5srv administration library within the "add_to_history()" function during the password history handling. This can be exploited to cause a heap-based buffer overflow when a principal changes the password and has a certain password history state.
Successful exploitation may allow execution of arbitrary code on a vulnerable Key Distribution Center (KDC) server. However, this requires that the administrator has performed a certain password policy change.
The vulnerability has been reported in version 1.3.5 and prior.
