"An authenticated remote attacker can execute arbitrary code in
Firebird SQL Server versions 2.5.7 and 3.0.2 by executing a malformed
SQL statement. The only known solution is to disable external UDF
libraries from being loaded. In order to achieve this, the default
configuration has changed to UdfAccess=None. This will prevent the
fbudf module from being loaded, but may also break other functionality
relying on modules.

For Debian 7 'Wheezy', these problems have been fixed in version
2.5.2.26540.ds4-1~deb7u4.

We recommend that you upgrade your firebird2.5 packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
