<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>A security issue has been discovered in xfig, a diagramming tool for the
interactive generation of figures under X11.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-40241">CVE-2021-40241</a>:
<p>A potential buffer overflow exists in the file src/w_help.c at line 55.
Specifically, the length of the string returned by getenv("LANG") may become
very long and cause a buffer overflow while executing the sprintf() function.
This vulnerability could potentially allow an attacker to execute arbitrary
code or cause a denial-of-service condition.</p></li>
</ul>
<p>For Debian 10 buster, this problem has been fixed in version
1:3.2.7a-3+deb10u1.</p>
<p>We recommend that you upgrade your xfig packages.</p>
<p>For the detailed security status of xfig please refer to
