DescriptionThe remote host is affected by the vulnerability described in GLSA-200502-08 (PostgreSQL: Multiple vulnerabilities)
PostgreSQL's contains several vulnerabilities:
John Heasman discovered that the LOAD extension is vulnerable to local privilege escalation (CAN-2005-0227).
It is possible to bypass the EXECUTE permission check for functions (CAN-2005-0244).
The PL/PgSQL parser is vulnerable to heap-based buffer overflow (CAN-2005-0244).
The intagg contrib module is vulnerable to a Denial of Service (CAN-2005-0246).
An attacker could exploit this to execute arbitrary code with the privileges of the PostgreSQL server, bypass security restrictions and crash the server.
There is no know workaround at this time.
SolutionAll PostgreSQL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose dev-db/postgresql
