<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>A flaw was found in the check_chunk_name() function of pngcheck, a tool to
verify the integrity of PNG, JNG and MNG files. This flaw allows an attacker
who can pass a malicious file to be processed by pngcheck to cause a temporary
denial of service.</p>
<p>For Debian 9 stretch, this problem has been fixed in version
2.3.0-7+deb9u1.</p>
<p>We recommend that you upgrade your pngcheck packages.</p>
<p>For the detailed security status of pngcheck please refer to
its security tracker page at:

these updates to your system and frequently asked questions can be
