CVE-2020-25681

A flaw was found in dnsmasq before version 2.83. A heap-based buffer overflow was discovered in the way RRSets are sorted before validating with DNSSEC data. An attacker on the network, who can forge DNS replies such as that they are accepted as valid, could use this flaw to cause a buffer overfl...

Heap overflow

A flaw was found in dnsmasq before version 2.83. A heap-based buffer overflow was discovered in the way RRSets are sorted before validating with DNSSEC data. An attacker on the network, who can forge DNS replies such as that they are accepted as valid, could use this flaw to cause a buffer overfl...

Arbitrary Code Execution

dnsmasq is vulnerable to arbitrary code execution. A heap-based buffer overflow in rfc1035.c:extractname due to the lack of length checks, which could be abused occurs when DNSSEC is enabled and before the receiving DNS entries are validated. A remote attacker who can create valid DNS replies is...
