Related CVE CVE-2019-19906

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 7 Wheezy, these problems have been fixed in version 2.1.25.dfsg1-6+deb7u2.

We recommend that you upgrade your cyrus-sasl2 packages.
