389-ds-base: 389-ds-base: Remote Code Execution and Denial of Service via heap buffer overflow

A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the schemaattrenumcallback function within the schema.c file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting...
