This issue allows remote attackers to execute arbitrary code by sending a long session cookie. A stack-based buffer overflow is a condition where a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially overwriting adjacent memory. **Recommendations** Update DIR-850L B1 to version 2.07WWB05 or later. Update DIR-818LW Bx to version 2.05b03beta03 or later. Update DIR-822 C1 to version 3.01WWb02 or later. Update DIR-823 A1 to version 1.00WWb05 or later. Update DIR-895L A1 to version 1.11WWb04 or later. Update DIR-890L A1 to version 1.09b14 or later. Update DIR-885L A1 to version 1.11WWb07 or later. Update DIR-880L A1 to version 1.07WWb08 or later. Update DIR-868L B1 to version 2.03WWb01 or later. Update DIR-868L C1 to version 3.00WWb01 or later. At the moment, there is no information about a newer version that contains a fix for DIR-817 Ax.
