Debian Security Advisory

DLA-2824-1 firebird3.0 -- LTS security update

Date Reported:

20 Nov 2021

Affected Packages:

firebird3.0

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2017-11509.

More information:

An authenticated remote attacker can execute arbitrary code in Firebird, a relational database based on InterBase 6.0, 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 9 stretch, this problem has been fixed in version 3.0.1.32609.ds4-14+deb9u1.

We recommend that you upgrade your firebird3.0 packages.
