Ten of these vulnerabilities can be exploited remotely. Some of them leading to provide root privileges on the remote system. And eleven can be exploited locally with most of them can be exploited in either default configuration or in a very common configuration. Some of the vulnerabilities can be chained together to obtain a full remote unauthenticated code execution and gain root privileges on the Exim Server. Most of the vulnerabilities discovered by the Qualys Research Team for e.g. CVE-2020-28017 affects all versions of Exim going back all the way to 2004 (going back to the beginning of its Git history 17 years ago)." -- Taylan ^ permalink raw reply [flat|nested] 4+ messages in thread
