389-ds-base: 389-ds-base: integer overflow in SASL packet length bypasses size limit leading to heap buffer overflow

An integer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, adding sizeofuint32t to a crafted SASL packet length prefix of 0xFFFFFFFC causes unsigned wraparound to zero, bypassing the nsslapd-maxsasliosize limit and leading to a heap buffer...
