+<p>Various vulnerabilities have been addressed in libexif, a library to
+parse EXIF metadata files.</p>
+
+<ul>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2016-6328">CVE-2016-6328</a>
+
+    <p>An integer overflow when parsing the MNOTE entry data of the input
+    file had been found. This could have caused Denial-of-Service (DoS)
+    and Information Disclosure (disclosing some critical heap chunk
+    metadata, even other applications' private data).</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2017-7544">CVE-2017-7544</a>
+
+    <p>libexif had been vulnerable to out-of-bounds heap read vulnerability
+    in exif_data_save_data_entry function in libexif/exif-data.c caused
+    by improper length computation of the allocated data of an ExifMnote
+    entry which could have caused denial-of-service or possibly information
+    disclosure.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2018-20030">CVE-2018-20030</a>
+
+    <p>An error when processing the EXIF_IFD_INTEROPERABILITY and
+    EXIF_IFD_EXIF tags within libexif version could have been exploited
+    to exhaust available CPU resources.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-0093">CVE-2020-0093</a>
+
+    <p>In exif_data_save_data_entry of exif-data.c, there was a possible out
+    of bounds read due to a missing bounds check. This could have lead to
+    local information disclosure with no additional execution privileges
+    needed. User interaction was needed for exploitation.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-12767">CVE-2020-12767</a>
+
+    <p>libexif had a divide-by-zero error in exif_entry_get_value in
+    exif-entry.c</p></li>
+
+</ul>
+
+<p>For Debian 8 <q>Jessie</q>, these problems have been fixed in version
+0.6.21-2+deb8u2.</p>
+
+<p>We recommend that you upgrade your libexif packages.</p>
