<title>Shorewall : Insecure temp file handling</title>
|

|
|

Shorewall is a high level tool for configuring Netfilter, the firewall
|
|
facility included in the Linux Kernel.

<description>
|
|
<p>
|
|
Shorewall uses temporary files and directories in an insecure manner. A
|
|
local user could create symbolic links at specific locations,
|
|
eventually overwriting other files on the filesystem with the rights of
|
|
the shorewall process.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could exploit this vulnerability to overwrite arbitrary
|
|
system files with root privileges, resulting in Denial of Service or
|
|
further exploitation.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time. All users should upgrade to
|
|
the latest available version of Shorewall.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All users should upgrade to the latest available version of Shorewall,
|
|
as follows:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=net-firewall/shorewall-1.4.10f"
|
|
# emerge ">=net-firewall/shorewall-1.4.10f"</code>
