Debian Security Advisory
DLA-1374-1 firebird2.5 -- LTS security update
- Date Reported:
- 11 May 2018
- Affected Packages:
- 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 184.108.40.206540.ds4-1~deb7u4.
We recommend that you upgrade your firebird2.5 packages.
