7-Zip is a file archiver with a high compression ratio. 7-Zip supports extracting from Compound Documents. Prior to version 25.0.0, a null pointer dereference in the Compound handler may lead to denial of service. Version 25.0.0 contains a fix cor the issue.

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20273-1 advisory.

    - Update to 25.01 (boo#1249130)
      * 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.

    - Update to 25.00:
      * bzip2 compression speed was increased by 15-40%.
      * deflate (zip/gz) compression speed was increased by 1-3%.
      * improved support for zip, cpio and fat archives.
      * CVE-2025-53816: Fixed input manipulation leading         to heap buffer overflow (bsc#1246706)
      * CVE-2025-53817: Fixed null pointer dereference leading         to denial of service (bsc#1246707)

    Various CVE fixes, most importantly CVE-2025-11001

    This also backports the Debian patch (PR unfortunately stalled upstream, with no communication from     upstream developers) to not echo passwords when dealing with encrypted archives.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 7-Zip is a file archiver with a high compression ratio. 7-Zip supports extracting from Compound Documents.
    Prior to version 25.0.0, a null pointer dereference in the Compound handler may lead to denial of service.
    Version 25.0.0 contains a fix cor the issue. (CVE-2025-53817)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of 7-Zip installed on the remote host is prior to 25.00. It is, therefore, affected by multiple vulnerabilities:

  - 7-Zip ZIP File Parsing Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote     attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this product is required to     exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists     within the handling of symbolic links in ZIP files. Crafted data in a ZIP file can cause the process to traverse to     unintended directories. An attacker can leverage this vulnerability to execute code in the context of a service     account. (CVE-2025-11001, CVE-2025-11002)

  - An error in Z-zip's RAR5 handler's error correction   for corrupted items can lead to a buffer overflow,   resulting in memory corruption and denial of service.
  (CVE-2025-53816)

  - A Null pointer dereference in 7-Zip's implementation of   the Compound handler can lead to denial of service at   specific values. (CVE-2025-53817)

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