**Name of the Vulnerable Software and Affected Versions** Dnsmasq versions prior to 2.76 **Description** The issue is related to improper bounds checking in the `do doctor` function of the Dnsmasq DNS server, which can lead to a buffer overflow in memory. This can be exploited by a remote attacker who controls a DNS server, allowing them to cause a denial of service or execute arbitrary code when the DNS server sends a specially crafted response larger than 4096 bytes. **Recommendations** For versions prior to 2.76, update to version 2.76 or later to resolve the issue. As a temporary workaround, consider restricting the size of DNS packets to prevent exploitation until a patch is applied.
