Avahi
Monthly
Avahi daemon versions 0.9rc2 and below can be remotely crashed through a denial of service attack by sending a specially crafted mDNS response with a recursive CNAME record pointing to itself, triggering unbounded recursion and stack exhaustion. This vulnerability affects systems using multicast record browsers, including those relying on nss-mdns for service discovery. A patch is available for affected installations.
Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In 0.9-rc2 and earlier, avahi-daemon can be crashed by sending 2 unsolicited announcements with CNAME resource records 2 seconds apart. [CVSS 6.5 MEDIUM]
Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In 0.9-rc2 and earlier, avahi-daemon can be crashed by sending unsolicited announcements containing CNAME resource records pointing it to resource records with short TTLs. [CVSS 6.5 MEDIUM]
