<vulnerable range="lt">5.0.2</vulnerable>
sysstat is a package containing a number of performance monitoring
utilities for Linux, including sar, mpstat, iostat and sa tools
There are two vulnerabilities in the way sysstat handles symlinks:
<li>The isag utility, which displays sysstat data in a graphical format,
creates a temporary file in an insecure manner.</li>
<li>Two scripts in the sysstat package, post and trigger, create temporary
files in an insecure manner.</li>
<impact type="normal">
Both vulnerabilities may allow an attacker to overwrite arbitrary files
under the permissions of the user executing any of the affected
A workaround is not currently known for this issue. All users are advised
to upgrade to the latest version of the affected package.
Systat users should upgrade to version 4.2 or later:
# emerge sync
# emerge -pv ">=app-admin/sysstat-5.0.2"
# emerge ">=app-admin/sysstat-5.0.2"</code>
