By sending a specially-crafted UDP packet to UDP port 5353, a remote attacker could exploit the vulnerability to cause the application to enter into an infinite loop. References:, Īvahi is vulnerable to a denial of service, caused by a NULL pointer dereference error within the avahi-core/socket.c. Remote attackers can perform a denial of service in WebRamp systems by sending a malicious UDP packet to port 5353, changing its IP address.Īvahi-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 mDNS IPv4 or IPv6 UDP packet to port 5353. TeamViewer remote desktop protocol uses ports 5938/TCP, 5939/TCP, 5353/UDPīackdoor.Optix.04.E (2004.02.10) - a backdoor trojan horse that gives an attacker unauthorized access to an infected computer by opening TCP port 5353 and listening for incoming connections. Plex Media Server uses port 5353 UDP locally for older Bonjour/Avahi network discovery.

In advance, thanks for any tips regarding this. I used TeamViewer to help another friend a few days ago with no problems.Īlso when I first attempted to connect with teamviewer today everything seemed correct, until I entered my friends partner ID then hit connect or establish connection or whatever (the button you press to get further and enter password), but I did not get any password prompt, instead it says I could not establish a connection.Īny tips? Tried to go on but it says it only have support for customers who pay for the program. I have also tried to reboot comp -> same resultĬhecked my proxy settings in IE9 (detect automatically)Ĭhecked proxy settings in teamviewer -> use the same as my web browser (default) I have tried to remove TeamViewer from control panel + registry, then run teamviewer -> same result. I'm not able to enter any partner ID that my friend gave me either. Probably you use a proxy server and must provide appropriate information in the options dialog."
After a few seconds I get this error msg (translated with Google from Norwegian to English): I were using TeamViewer (v.6) today and could not establish an partner ID, instead it appears only a "-" in the partner ID field.
