Beskrivelse:
Der er rapporteret en sårbarhed i Ethereal, som kan udnyttes af ondsindede personer til at forårsage et DoS (Denial of Service) og potentielt kompromittere en brugers system.

Sårbarheden skyldes en ikke-kontrolleret buffer i dissect_ospf_v3_address_prefix() funktionen af OSPF protokol afkoderen (packet-ospf.c) ved konvertering af binære data til læsbare strenge. Dette kan udnyttes til at forårsage et stack-baseret buffer overflow og kan potentielt gøre det muligt at eksekvere vilkårlig kode på bestemte platforme.

Sårbarheden er rapporteret i ethereal-0.10.12 RPM fra Red Hat Fedora Core 3 og i version 0.8.20 til 0.10.13.
