Overview: The host is running PostgreSQL and is prone to integer overflow vulnerability.
Vulnerability Insight: The flaw is due to an integer overflow error in 'src/backend/executor/nodeHash.c', when used to calculate size for the hashtable for joined relations.
Impact: Successful exploitation could allow execution of specially-crafted sql query which once processed would lead to denial of service (postgresql daemon crash).
Impact Level: Application
Affected Software/OS: PostgreSQL version 8.4.1 and prior and 8.5 through 8.5alpha2
