-
CVE-2017-5613: A format string injection vulnerability that allows an attacker to supply arbitrary format strings to cgiemail and cgiecho. This could be used by a local attacker with permissions to provide a cgiemail template to execute code as the webserver user.
-
CVE-2017-5614: An open redirect vulnerability in cgiemail and cgiecho binaries that could be exploited by a local attacker to force a redirect to an arbitrary URL. The redirects are now limited to the domain that handled the request.
-
CVE-2017-5615: A vulnerability in cgiemail and cgiecho binaries that allowed injection of additional HTTP headers. Newline characters are now stripped from the redirect location to protect against this.
-
CVE-2017-5616: A reflected cross-site scripting (XSS) vulnerability in cgiemail and cgiecho binaries due to missing escaping of the addendum parameter. The output is now HTML escaped to prevent this vulnerability.
