Description:
Sipera VIPER Lab has reported some vulnerabilities in Grandstream HandyTone HT488, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) A boundary error exists within the processing of SIP messages. This can be exploited to cause a buffer overflow by sending a specially crafted SIP INVITE message.
2) An error within the IP stack implementation can be exploited to crash an affected device by sending a large number of fragmented IP packets to port 5060.
Solution:
Use the device in a trusted network environment only.
