Technical details
This is an out-of-bounds write vulnerability caused by improper validation of the URL component length in pre-authenticated HTTP messages. The vulnerable code does not check the URL length before appending additional data to it, resulting in a buffer overflow in memory. An unauthenticated remote attacker on the network can exploit this by sending a malformed HTTP request, triggering a crash and denial-of-service condition. A patch is available via update to version V2.70 or later.
