More information:

There has been an out-of-bounds write in Cyrus SASL leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash was ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl.

For Debian 8 Jessie, this problem has been fixed in version 2.1.26.dfsg1-13+deb8u2.

We recommend that you upgrade your cyrus-sasl2 packages.
