Vulnerability from certfr_avis - Published: - Updated:

Deux vulnérabilités permettant une modification arbitraire du cache DNS et un déni de service à distance ont été corrigées dans dnsmasq.

Description

Une faiblesse dans l'aléa du choix des identifiants de transactions et des numéros de ports sources permet la modification arbitraire du cache DNS via des requêtes spécifiquement construites. De plus, une vulnérabilité lors du renouvellement du bail DHCP d' un client est exploitable pour provoquer un déni de service à distance.
