Description



Exim developers report:



If your Exim server accepts TLS connections, it is vulnerable. This does


not depend on the TLS libray, so both, GnuTLS and OpenSSL are affected.


The vulnerability is exploitable by sending a SNI ending in a


backslash-null sequence during the initial TLS handshake. The exploit


exists as a POC. For more details see the document qualys.mbx
