QID 670889

QID 670889: EulerOS Security Update for avahi (EulerOS-SA-2021-2352)

Avahi is a system which facilitates service discovery on a local network -- this means that you can plug your laptop or computer into a network and instantly be able to view other people who you can chat with, find printers to print to or find files being shared. This kind of technology is already found in MacOS X (branded 'Rendezvous', 'Bonjour' and sometimes 'ZeroConf') and is very convenient. Security Fix(es): A flaw was found in avahi in versions 0.6 up to 0.8. The event used to signal the termination of the client connection on the avahi Unix socket is not correctly handled in the client_work function, allowing a local attacker to trigger an infinite loop. The highest threat from this vulnerability is to the availability of the avahi service, which becomes unresponsive after this flaw is triggered.(CVE-2021-3468)
