The specific flaw exists within the way Samba handles GetAliasMembership requests. When parsing the data send in the request Samba uses the field 'sids' to create a heap allocation but then uses another field, 'num_sids', to write data to the allocation. Because there is no check to see if 'num_sids' is smaller than 'sids' this could result in a heap buffer overflow that could lead to remote code execution.
Samba has issued an update to correct this vulnerability. More details can be found at:
