+"Dear $owner_name,
+
+CAcert recently became aware that some of the certificates signed by CAcert pose a security
+risk because they are backed by private keys that are vulnerable to attack.
+
+The security issues identified are:
+Private keys with a small key size. These keys are vulnerable to brute force attack.
+Private keys with an unsafe exponent. These keys are vulnerable to some specialised attacks.
+Private keys generated by a compromised version of OpenSSL distributed by Debian.
+
+You received this email because a certificate issued to you is vulnerable:
+
+Server Certificate, Serial $cert_serial, expiring $cert_expire, CN $cert_CN
+
+To rectify the problem CAcert will revoke all vulnerable certificates (including yours) on $action_date.
+CAcert will no longer accept vulnerable certificate requests for signing. In future all Certficate
+Signing Requests must be backed by private keys with a key length at least 2048 bits and no other known vulnerabilities.
+
+You should submit a new Certificate Signing Request of acceptable strength as soon as possible
+and replace your existing certificate.
+
+If you are interested in background information on this change please refer to this document:
