Update 7-Zip to fix a serious vulnerability
If you’re using the popular utility 7-Zip and don’t update to the latest version, you could be leaving your PC vulnerable, allowing bad guys to:
- install programs on your PC,
- view, edit, or delete data, or
- create new user accounts with full access rights.
On May 1, 2018, the Center for Internet Security issued advisory #2018-049 outlining the threat. They rate the risk to all users as high, though as yet, “There are currently no reports of this vulnerability being exploited in the wild.”
Since then, media outlets such as PC Gamer have also reported the vulnerability.
To mitigate the threat, you should be using version 18.05 or higher.
To prevent vulnerability to your PC, CIS recommends:
- Update 7-Zip to the latest version. Updates for 7-Zip can be found at 7-zip.org
- Don’t run 7-Zip with Administrator privileges
