unbound: command injection with data coming from a specially crafted IPSECKEY answer
Unbound 1.6.4 through 1.9.4 contain a vulnerability in the ipsec module that can cause shell code execution after receiving a specially crafted answer. This issue can only be triggered if unbound was compiled with `--enable-ipsecmod` support, and ipsecmod is enabled and used in the configuration.
A shell command injection vulnerability was discovered in the way unbound handles DNS queries for systems with a public key used for IPsec. When ipsecmod is enabled, a malicious DNS server could send a DNS reply which would be used during a following DNS query to execute shell commands with the privileges of the unbound process. The same attack could be performed by an attacker who can modify data transmitted ov
