  <title>PostgreSQL: Insecure temporary file use in make_oidjoins_check</title>
  <synopsis>
    The make_oidjoins_check script, part of the PostgreSQL package, is
    vulnerable to symlink attacks, potentially allowing a local user to
    overwrite arbitrary files with the rights of the user running the utility.

    <p>
    PostgreSQL is an open source database based on the POSTGRES database
    management system. It includes several contributed scripts including
    the make_oidjoins_check script.
    </p>
  </background>
  <description>
    <p>
    The make_oidjoins_check script insecurely creates temporary files in
    world-writeable directories with predictable names.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could create symbolic links in the temporary files
    directory, pointing to a valid file somewhere on the filesystem. When
    make_oidjoins_check is called, this would result in file overwrite with
    the rights of the user running the utility, which could be the root
    user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All PostgreSQL users should upgrade to the latest version:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=dev-db/postgresql-7.4.5-r2"
    # emerge "&gt;=dev-db/postgresql-7.4.5-r2"</code>
    <p>
    Upgrade notes: PostgreSQL 7.3.x users should upgrade to the latest
    available 7.3.x version to retain database compatibility.
    </p>
