USN-4461-1: Ark vulnerability
18 August 2020
Ark could be made to write files as your login if it opened a specially crafted file.
Releases
Packages
- ark - archive utility
Details
Dominik Penner discovered that Ark did not properly sanitize zip archive
files before performing extraction. An attacker could use this to construct
a malicious zip archive that, when opened, would create files outside the
extraction directory.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04
Ubuntu 18.04
After a standard system update you need to restart Ark to make all
the necessary changes.
