CVE-2012-3429 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.07% chance of exploitation in the next 30 days.
