Description:
Emanuele Aina has reported a security issue in Avahi, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The security issue is caused due to an "assert()" error when receiving empty TXT data over D-Bus for registration. This can be exploited to terminate the Avahi daemon by sending empty TXT data.
The security issue is reported in versions prior to 0.6.20.
Solution:
Update to version 0.6.20.
Provided and/or discovered by:
Emanuele Aina
