Dynamic DNS Update Client for Linux HTTP response buffer overflow
| dducl-httpresponse-bo (46696) |  High Risk |
Description:
Dynamic DNS Update Client for Linux is vulnerable to a stack-based buffer overflow, caused by improper bounds checking related to a missing length check in the GetNextLine() function. By sending a specially-crafted HTTP response via man-in-the-middle techniques, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
