    Debian Bug     : 1111068

    Multiple vulnerabilities were discovered in p7zip, a now unmaintained
    fork of 7-Zip, a file archiver handling multiple formats.

    To address these security vulnerabilities, whose fixes are
    unfortunately not isolated, this update replaces p7zip with 7-Zip v25
    (which now supports GNU/Linux natively), slightly modified to make it
    reasonably compatible with p7zip.

    CVE-2022-47069

        heap-buffer-overflow vulnerability via the function
        NArchive::NZip::CInArchive::FindCd

    CVE-2023-31102

        Ppmd7.c allows an integer underflow and invalid read operation via
        a crafted 7Z archive.

    CVE-2023-40481

        SquashFS File Parsing Out-Of-Bounds Write RCE

    CVE-2023-52168

        heap-based buffer overflow in NTFS handler

    CVE-2023-52169

        out-of-bounds read in NTFS handler

    CVE-2024-11612

        CopyCoder Infinite Loop Denial-of-Service

    CVE-2025-11001

        ZIP File Parsing Directory Traversal RCE

    CVE-2025-11002

        ZIP File Parsing Directory Traversal RCE

    CVE-2025-53817

        null pointer dereference in the Compound handler may lead to
        denial of service

    CVE-2025-55188

        does not always properly handle symbolic links

    For Debian 11 bullseye, these problems have been fixed in version
    16.02+really25.01+dfsg-0+deb11u1.

    We recommend that you upgrade your p7zip packages.
