Impact:
Denial of service via network, Execution of arbitrary code via network, Root access via network

Description:
A vulnerability was reported in Kerberos. A remote user may be able to execute arbitrary code on the target system.
A remote user can send specially crafted data to cause the gssrpc__svcauth_gssapi() function in 'src/lib/rpc/svc_auth_gssapi.c' to attempt to free an uninitialized 'creds' parameter [CVE-2007-2442]. This may allow the remote user to execute arbitrary code on the target system with the privileges of the target service (root privileges), or to crash the target service.
A remote user can send specially crafted data to cause the gssrpc__svcauth_unix() function in 'src/lib/rpc/svc_auth_unix.c' to potentially execute arbitrary code.
MIT credits Wei Wang of McAfee Avert Labs with discovering these vulnerabilities.
