Actually my client (a bank in this case) is using GPG 1.2.3 and does not want to upgrade right away. Is there a patch available for GPG 1.2.3 which can fix this issue ? Appreciate any help.

It's possible. 1.2.3 is also QUITE old.

There you have it. The most direct solution would appear to be for the client to
upgrade to a more current release of GnuPG. (>= 1.4.9)
