Description

Clients sending negotiation requests with invalid flags could crash the kerberos server (CVE-2009-0845).

GSS-API clients could crash when reading from an invalid address space (CVE-2009-0844).

Invalid length checks could crash applications using the kerberos ASN.1 parser (CVE-2009-0847).

Under certain circumstances the ASN.1 parser could free an uninitialized pointer which could crash a kerberos server or even lead to execution of arbitrary code (CVE-2009-0846).
