Description:
Seth Fogie has reported a security issue in iTunes, which potentially can be exploited by malicious people to cause a DoS (Denial of Service).
The security issue is caused due to iTunes failing to authenticate the source of shared music lists received via multicast. This can be exploited via a MDNS packet with spoofed source IP address to delete the list of music shared by other users from multiple users' iTunes and thereby potentially causing a DoS. It is also possible to modify the name of entries in the list via specially-crafted packets.
The security issue has been reported in version 6.0. Other versions may also be affected.
Solution:
Restrict use of the shared music feature to within trusted networks only.
