+<p>Richard Weinberger reported that unsquashfs in squashfs-tools, the tools
+to create and extract Squashfs filesystems, does not check for duplicate
+filenames within a directory. An attacker can take advantage of this
+flaw for writing to arbitrary files to the filesystem if a malformed
+Squashfs image is processed.</p>
+
+<p>For the oldstable distribution (buster), this problem has been fixed
+in version 1:4.3-12+deb10u2.</p>
+
+<p>For the stable distribution (bullseye), this problem has been fixed in
+version 1:4.4-2+deb11u2.</p>
+
+<p>We recommend that you upgrade your squashfs-tools packages.</p>
+
+<p>For the detailed security status of squashfs-tools please refer to its
