    Package : squashfs-tools
    CVE ID : CVE-2021-41072
    Debian Bug : 994262

    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.

    For the oldstable distribution (buster), this problem has been fixed
    in version 1:4.3-12+deb10u2.

    For the stable distribution (bullseye), this problem has been fixed in
    version 1:4.4-2+deb11u2.

    We recommend that you upgrade your squashfs-tools packages.

    For the detailed security status of squashfs-tools please refer to its
    security tracker page at: https://security-tracker.debian.org/tracker/squashfs-tools
