Synopsis


PostgreSQL contains a vulnerability that could result in SQL privilege escalation.

Background


PostgreSQL is an open source object-relational database management system.

Affected packages



Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-db/postgresql < 8.0.13 >= 8.0.13
*>= 7.4.17
*>= 7.3.19

Description


An error involving insecure search_path settings in the SECURITY DEFINER functions has been reported in PostgreSQL.

Impact


If allowed to call a SECURITY DEFINER function, an attacker could gain the SQL privileges of the owner of the called function.

Workaround


There is no known workaround at this time.

Resolution


All PostgreSQL users should upgrade to the latest version and fix their SECURITY DEFINER functions:

    # emerge --sync
    # emerge --ask --oneshot --verbose "dev-db/postgresql"

In order to fix the SECURITY DEFINER functions, PostgreSQL users are advised to refer to the PostgreSQL documentation: http://www.postgresql.org/docs/techdocs.77
