      yay, a new stable 7-zip version that is no longer a beta or an alpha

    • #2402946

      Looks as though we’ll have to wait a short while for the standalone console version!

        yeah, newest p7zip currently at 16.02+dfsg-8 via debian/ubuntu.
        There will no doubt be dependancy changes and testing involved, so expect a wait…

      7Zip Update to v24.08
      for 32bit, 64bit and ARM64
      August 11th 2024

      History ref: https://www.7-zip.org/history.txt

      – The bug in 7-Zip 24.00-24.07 was fixed:
      For creating a zip archive: 7-Zip could write extra zero bytes after the end of the archive, if a file included to archive cannot be compressed to a size smaller than original. The created zip archive is correct except for the useless zero bytes after the end of the archive. When unpacking such a zip archive, 7-Zip displays a warning: “WARNING: There are data after the end of archive”.

      – The bug was fixed: there was a leak of GDI objects (internal resources in Windows) in “Confirm File Replace” window, causing problems after 1600 displays of “Confirm File Replace” window from same running 7-Zip process.

      – Some optimizations for displaying file icons in 7-Zip File Manager and in “Confirm File Replace” window.

      – Some bugs were fixed.

        Users of 7-zip should update to the new 7-zip 24.09

        7-Zip Mark-of-the-Web Bypass Vulnerability
        ZDI-25-045
        ZDI-CAN-25456

        CVE-2025-0411

        This vulnerability allows remote attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of 7-Zip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

        The specific flaw exists within the handling of archived files. When extracting files from a crafted archive that bears the Mark-of-the-Web, 7-Zip does not propagate the Mark-of-the-Web to the extracted files. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user…

        Fixed in 7-Zip version 24.09

        • #2747614

          Not completely fixed in 24.09. Per the SANS Institute’s Diary entry on February 10, 2025, one still has to enable the propagation of the MoW via a drop-down menu entry that’s documented in the Diary entry. This includes the latest version as well according to the diary entry, and I found that to be true on my own machines. On both machines which are running 24.09, I had to change the entry in the drop down box mentioned in the diary entry.
