389-ds-base before versions 1.3.5.17 and 1.3.6.10 is vulnerable to an invalid pointer dereference in the way LDAP bind requests are handled. A remote unauthenticated attacker could use this flaw to make ns-slapd crash via a specially crafted LDAP bind request, resulting in denial of service.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
The product dereferences a pointer that it expects to be valid but is NULL.
