    Package        : binwalk
    Version        : 2.3.1+dfsg1-1+deb11u1
    CVE ID         : CVE-2022-4510


    A path traversal vulnerability was identified in binwalk. By crafting
    a malicious PFS filesystem file, an attacker can get binwalk's PFS
    extractor to extract files at arbitrary locations when binwalk is run
    in extraction mode (-e option). Remote code execution can be achieved
    by building a PFS filesystem that, upon extraction, would extract a
    malicious binwalk module into the folder .config/binwalk/plugins.

    For Debian 11 bullseye, this problem has been fixed in version
    2.3.1+dfsg1-1+deb11u1.

    We recommend that you upgrade your binwalk packages.

    For the detailed security status of binwalk please refer to
    its security tracker page at:
