Kwetsbaarheden ontdekt in CUPS

All disputes related to or arising from the use of this advisory will be submitted to the competent court in The Hague. This choice of means also applies to the court in summary proceedings.
Feiten
Onlangs zijn er door een onderzoeker een aantal kwetsbaarheden ontdekt in CUPS die kunnen leiden tot Remote Code Execution. Deze zijn bekend gemaakt als "9.9 RCE affecting all GNU/Unix systems".
Interpretaties
Door een aaneenschakeling van de vier kwetsbaarheden, kan een kwaadwillende onder bepaalde omstandigheden willekeurige code uitvoeren binnen de context van de CUPS-service.
Oplossingen
Er zijn op dit moment nog geen patches beschikbaar om de kwetsbaarheden te verhelpen in CUPS versies lager dan 2.0.1. Tot het moment dat de updates beschikbaar komen is het handelingsperspectief om de cups-browse daemon uit te schakelen. Tevens is het raadzaam om te controleren of CUPS onbereikbaar is vanaf publieke netwerken. Controleer of verkeer van en naar UDP poort 631 wordt geblokkeerd. Hiermee wordt het risico van misbruik vanaf publieke netwerken verminderd. **UPDATE** Er zijn patches beschikbaar gesteld om de kwetsbaarheden te verhelpen. Deze zijn doorgevoerd in de distributies van GNU/Linux systemen.
