Debian DLA-1374-1 : firebird2.5 security update

high Nessus Plugin ID 109734

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

Solution

Upgrade the affected packages.
