CVE-2025-68276
MediumSummary
Avahi to system, który ułatwia odkrywanie usług w lokalnej sieci za pomocą protokołu mDNS/DNS-SD. W wersjach 0.9-rc2 i wcześniejszych, nieuprzywilejowani lokalni użytkownicy mogą spowodować awarię avahi-daemon, tworząc przeglądarki rekordów z ustawioną flagą AVAHI_LOOKUP_USE_WIDE_AREA przez D-Bus.
Risk Assessment
Atakujący mogą destabilizować usługi sieciowe, co może prowadzić do przerw w dostępności systemu. To może wpłynąć na działanie aplikacji korzystających z Avahi w organizacji.
Recommendation
Zaleca się aktualizację Avahi do najnowszej wersji, aby zniwelować ryzyko związane z tą podatnością. Dodatkowo, warto ograniczyć dostęp do D-Bus dla nieuprzywilejowanych użytkowników.
