Description
A heap-use-after-free error exists in the
ngx http ssl module module. This occurs when the ssl verify client directive is set to "on" or "optional," and the ssl ocsp directive is set to "on" or the leaf parameters are configured with a resolver. An unauthenticated attacker can send requests that trigger this condition, potentially leading to limited data modification or the restarting of the NGINX worker process.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
