Title:	avahi -- denial of service
Summary:	avahi -- denial of service
Description:	The remote host is missing an update to the system as announced in the referenced advisory. The following packages are affected: avahi avahi-app avahi-autoipd avahi-gtk avahi-libdns avahi-qt3 avahi-qt4 avahi-sharp CVE-2011-1002 avahi-core/socket.c in avahi-daemon in Avahi before 0.6.29 allows remote attackers to cause a denial of service (infinite loop) via an empty (1) IPv4 or (2) IPv6 UDP packet to port 5353. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-2244. CVE-2010-2244 The AvahiDnsPacket function in avahi-core/socket.c in avahi-daemon in Avahi 0.6.16 and 0.6.25 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a DNS packet with an invalid checksum followed by a DNS packet with a valid checksum, a different vulnerability than CVE-2008-5081. Solution: Update your system with the appropriate patches or software upgrades. http://secunia.com/advisories/43361/ https://bugzilla.redhat.com/show_bug.cgi?id=667187 http://www.vuxml.org/freebsd/8b986a05-4dbe-11e0-8b9a-02e0184b8d35.html
