Subject Name: MIT Kerberos
Subject Summary: Kerberos Network Authentication System
Subject Home: http://web.mit.edu/kerberos/
Subject Versions: * <= 1.5.1
Vulnerability Id: CVE-2006-6143, cert:VU#481564, CVE-2006-6144,
cert:VU#831452, cert:TA07-009B
Vulnerability Scope: global (not OpenPKG specific)
Attack Feasibility: run-time
Attack Vector: remote network
Attack Impact: denial of service, arbitrary code execution
Description:
According to vendor security advisories [0][1], two security issues
exist in the Kerberos network authentication system implementation
MIT Kerberos [2]. First, the RPC library could call an uninitialized
function pointer, which created a security vulnerability for
kadmind(8). Second, the GSS-API "mechglue" layer could fail to
initialize some output pointers, causing callers to attempt to free
uninitialized pointers. This caused another security vulnerability
in kadmind(8).
