VectorAV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Name of the Vulnerable Software and Affected Versions Treck TCP/IP stack versions prior to 4.7.1.27
Description The issue is related to the mishandling of '0' termination in DHCP, which can lead to a buffer overflow in the stack. This can potentially allow a remote attacker to cause a denial of service.
Recommendations For versions prior to 4.7.1.27, update to version 4.7.1.27 or later to resolve the issue. As a temporary workaround, consider restricting access to the DHCP service until a patch is available.
