Synopsis:	Important: krb5 security update
Issue date:	2007-06-26
CVE Names:	CVE-2007-2442 CVE-2007-2443 CVE-2007-2798

David Coffey discovered an uninitialized pointer free flaw in the RPC
library used by kadmind. On Scientific Linux 4 and 5, glibc
detects attempts to free invalid pointers. A remote unauthenticated
attacker who can access kadmind could trigger this flaw and cause kadmind
to crash. (CVE-2007-2442)

David Coffey also discovered an overflow flaw in the RPC library used by
kadmind. On Scientific Linux, exploitation of this flaw is limited
to a denial of service. A remote unauthenticated attacker who can access
kadmind could trigger this flaw and cause kadmind to crash. (CVE-2007-2443)

A stack buffer overflow flaw was found in kadmind. An authenticated
attacker who can access kadmind could trigger this flaw and potentially
execute arbitrary code on the Kerberos server. (CVE-2007-2798)
