CVE-2012-3429: Martin Nagy BIND-Dyndb-LDAP

Medium severity, CVSS 5.0. EPSS: 3.1% chance of exploitation in the next 30 days.

The dns_to_ldap_dn_escape function in src/ldap_convert.c in bind-dyndb-ldap 1.1.0rc1 and earlier does not properly escape distinguished names (DN) for LDAP queries, which allows remote DNS servers to cause a denial of service (named service hang) via a "$" character in a DN in a DNS query.

Affected products

• Martin Nagy BIND-Dyndb-LDAP: up to and including 1.1.0; version 0.1.0 only; version 0.2.0 only; version 1.0.0 only; version 1.1.0 only
