CVE-2020-16116
Published: 3 August 2020
In kerfuffle/jobs.cpp in KDE Ark before 20.08.0, a crafted archive can install files outside the extraction directory via ../ directory traversal.
From the Ubuntu Security Team
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.
