The updated packages have been patched to correct this issue. Update packages for MES5 were missing with the MDVSA-2010:202 advisory. This advisory provides the update packages.

5de8b3fb4816aafe3b8e24e0543bd5f4519a3ac80cdb3555bd7c8f5dccf79f6eMIT krb5 Security Advisory 2010-006 - When the MIT krb5 KDC receives certain Kerberos TGS request messages, it may dereference an uninitialized pointer while processing authorization data, causing a crash, or in rare cases, unauthorized information disclosure, ticket modification, or execution of arbitrary code. The crash may be triggered by legitimate requests. This is an implementation vulnerability in MIT krb5, and not a vulnerability in the Kerberos protocol.
