Javier Fernandez-Sanguino Pena from the Debian Security Audit
|
|
Project discovered that the 'mysqlaccess' script creates temporary
|
|
files in world-writeable directories with predictable names.
|

|
<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 the mysqlaccess script is executed, this would result in the file
|
|
being overwritten with the rights of the user running the software,
|
|
which could be the root user.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All MySQL users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-db/mysql-4.0.22-r2"</code>
|
