<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>Various minor vulnerabilities have been addredd in libexif, a library to
parse EXIF metadata files.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2018-20030">CVE-2018-20030</a>
<p>This issue had already been addressed via DLA-2214-1. However, upstream
provided an updated patch, so this has been followed up on.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-13112">CVE-2020-13112</a>
<p>Several buffer over-reads in EXIF MakerNote handling could have lead
to information disclosure and crashes. This issue is different from
already resolved <a href="https://security-tracker.debian.org/tracker/CVE-2020-0093">CVE-2020-0093</a>.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-13113">CVE-2020-13113</a>
<p>Use of uninitialized memory in EXIF Makernote handling could have
lead to crashes and potential use-after-free conditions.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-13114">CVE-2020-13114</a>
<p>An unrestricted size in handling Canon EXIF MakerNote data could have
lead to consumption of large amounts of compute time for decoding
EXIF data.</p></li>
</ul>
<p>For Debian 8 <q>Jessie</q>, these problems have been fixed in version
0.6.21-2+deb8u3.</p>
<p>We recommend that you upgrade your libexif packages.</p>
