The version of 7-Zip installed on the remote host is prior to 25.01. It is, therefore, affected by a security bypass vulnerability. The code for handling symbolic links has been changed to provide greater security when extracting files from archives. Command line switch -snld20 can be used to bypass default security checks when creating symbolic links.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-6e0627440a advisory.

    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-2023-31102

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

        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.
