Name of the Vulnerable Software and Affected Versions Linksys E8450 version 1.2.00.360516

Description The issue is related to a buffer overflow vulnerability in the Linksys E8450 Wi-Fi router's firmware. This vulnerability is caused by the lack of size verification when copying input data, specifically in the dhcpstart ip field, which is then copied to the stack. An attacker could exploit this vulnerability to cause a denial of service.

Recommendations For version 1.2.00.360516, as a temporary workaround, consider restricting access to the vulnerable dhcpstart ip field until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
