Debian Security Advisory

DLA-1374-1 firebird2.5 -- LTS security update

Date Reported:

11 May 2018

Affected Packages:

firebird2.5

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 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.
