Synopsis:	Important: krb5 security update
Issue date:	2007-09-04
CVE Names:	CVE-2007-3999 CVE-2007-4000

Tenable Network Security discovered a stack buffer overflow flaw in the RPC
library used by kadmind. A remote unauthenticated attacker who can access
kadmind could trigger this flaw and cause kadmind to crash. On Red Hat
Enterprise Linux 5 it is not possible to exploit this flaw to run arbitrary
code as the overflow is blocked by FORTIFY_SOURCE. (CVE-2007-3999)

Garrett Wollman discovered an uninitialized pointer flaw in kadmind. A
remote unauthenticated attacker who can access kadmind could trigger this
flaw and cause kadmind to crash. (CVE-2007-4000)
