<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.

PostgreSQL is an open source database based on the POSTGRES database
|
|
management system. It includes several contributed scripts including
|
|
the make_oidjoins_check script.

<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 ">=dev-db/postgresql-7.4.5-r2"
|
|
# emerge ">=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.
|
|
