(1.5.3) Security diagnostics added
(1.5.3) Closed an Endemic Security Hole

The following group of minor enhancements was added to the Firebird v.1.5.3 point release.-

(1.5.3) Two ISQL Improvements

C. Valderrama, D. Ivanov

Command line switch -b to bail out on error when used in non-interactive mode.
Return an error code to the operating system from command-line isql

(1.5.3) Make Old Column Naming Convention available

Paul Reeves

Added OldColumnNaming parameter to firebird.conf to allow users to revert to pre-V1.5 column naming in Select expressions.

(1.5.3) Security diagnostics added

Alex Peshkoff

Attempts to send signals via a missing gds_relay may be an exploit attempt. They are now logged.

(1.5.3) Closed an Endemic Security Hole

Alex Peshkoff

Previously, a user could log into a server on a Unix/Linux host remotely, using a Linux UID and password accepted on that host. It was recognised as a security hole and fixed in Firebird 2 development. It is an endemic security bug in previous versions and InterBase. The security fix has been back-ported to Firebird 1.5.3: a UID received from the client side is now not trusted.
