A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.10 - Ubuntu 19.04 - Ubuntu 18.04 LTS


FreeTDS could be made to crash or run programs if it received specially crafted network traffic.

Software Description: - freetds: libraries for connecting to MS SQL and Sybase SQL servers


Felix Wilhelm discovered that FreeTDS incorrectly handled certain types after a protocol downgrade. A remote attacker could use this issue to cause FreeTDS to crash, resulting in a denial of service, or possibly execute arbitrary code.
