+<p>Issues were found in ncurses, a collection of shared libraries for
+terminal handling, which could lead to denial of service.</p>
+
+<ul>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-39537">CVE-2021-39537</a>
+
+    <p>It has been discovered that the <code>tic(1)</code> utility is susceptible to a
+    heap overflow on crafted input due to improper bounds checking.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2023-29491">CVE-2023-29491</a>
+
+    <p>Jonathan Bar Or, Michael Pearse and Emanuele Cozzi have discovered
+    that when ncurses is used by a setuid application, a local user can
+    trigger security-relevant memory corruption via malformed data in a
+    terminfo database file found in <code>$HOME/.terminfo</code> or reached via the
+    <code>TERMINFO</code> or <code>TERM</code> environment variables.</p>
+
+    <p>In order to mitigate this issue, ncurses now further restricts
+    programs running with elevated privileges (setuid/setgid programs).
+    Programs run by the superuser remain able to load custom terminfo
+    entries.</p>
+
+    <p>This change aligns ncurses' behavior in buster-security with that of
+    Debian Bullseye's latest point release (6.2+20201114-2+deb11u2).</p></li>
+
+</ul>
+
+<p>For Debian 10 buster, these problems have been fixed in version
+6.1+20181013-2+deb10u5.</p>
+
+<p>We recommend that you upgrade your ncurses packages.</p>
