Name of the Vulnerable Software and Affected Versions
Dnsmasq versions prior to 2.78
Description
The issue is caused by a heap-based buffer overflow in the dynamic memory of the DNS server. This can be exploited by a remote attacker using a specially crafted IPv6 request, potentially allowing them to cause a denial of service or execute arbitrary code.
Recommendations
For versions prior to 2.78, update to version 2.78 or later to resolve the issue. As a temporary workaround, consider restricting access to the DNS server to minimize the risk of exploitation.
