Description:
Two vulnerabilities have been reported in Avahi, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
1) An error within the handling of mDNS name conflicts can be exploited to disconnect mDNS/DNS-SD services.
2) An unspecified error in avahi-core can be exploited to cause a buffer overflow and may allow arbitrary code execution with privileges of the "avahi" user.
The vulnerabilities have been reported in versions prior to 0.6.10.
Solution:
Update to version 0.6.10.
