A buffer overflow vulnerability in the library "libclinkc" of the Zyxel VMG8825-T50K firmware version 5.50(ABOM.8)C0 could allow an unauthenticated attacker to cause denial of service (DoS) conditions by sending a crafted HTTP request to a vulnerable device.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
