ZStandard and Brotli is not default methods of 7-zip, so these archives are considered Py7zr try checking symbolic links strictly and raise ValueError when bad link is requested,īut it does not guarantee to block all the bad cases. Supported algorithmsĪ feature handling symbolic link is basically compatible with p7zip implementation,īut not work with original 7-zip because the original does not implement the feature.
Py7zr is also able to encrypt and decrypt data using 3rd party encryption library. It also supports ZStandard, Brotli and PPMd with third party libraries. Py7zr supports algorithms and filters which lzma module and liblzma support,Īnd supports BZip2 and Deflate that are implemented in python core libraries, Matteo Cosentino for notification and coorporation on security improvement. You are recommend to update immediately to version 0.20.2 or later, 0.19.2 or 0.18.12 Īffected versions are vulnerable to Directory Traversal due to insufficient checks in the ‘py7zr.py’ and ‘helpers.py’ files Version 0.20.0, 0.19.0, 0.18.10 or before has a vulnerability for path traversal attack.ĭetails are on “CVE-2022-44900: path traversal vulnerability in py7zr” disclose article.

Keka needs a helper to set itself as the default application. Set Keka as the default extraction application The newest Keka, but relax, the old versions will be here.ġ9.2 MB | For Mac OS X 10.7 | Context menuġ9.3 MB | For Mac OS X 10.6 | Context menu Over the years your Mac will become older and will not support If you find a bug or have something to report, head over to Issues.ģ6.5 MB | Requires Mac OS X 10.10 or newer You can test the newest features of Keka before they are released. If the files are really huge and they do not fit your mail or server, just split them into pieces.ĭon't worry, they will still expand to produce your original file :) Keka can create files in these formats:
