<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>Different flaws have been found in leptonlib, an image processing
library. </p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2018-7186">CVE-2018-7186</a>
<p>Leptonica did not limit the number of characters in a %s format
argument to fscanf or sscanf, that made it possible to remote
attackers to cause a denial of service (stack-based buffer overflow)
or possibly have unspecified other impact via a long string.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2018-7440">CVE-2018-7440</a>
<p>The gplotMakeOutput function allowed command injection via a
$(command) approach in the gplot rootname argument. This issue
existed because of an incomplete fix for <a href="https://security-tracker.debian.org/tracker/CVE-2018-3836">CVE-2018-3836</a>.</p></li>
</ul>
<p>For Debian 7 <q>Wheezy</q>, these problems have been fixed in version
1.69-3.1+deb7u2.</p>
<p>We recommend that you upgrade your leptonlib packages.</p>
<p>Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
