Ark was found to allow arbitrary file overwrite, possibly allowing arbitrary code execution.
|Package||kde-apps/ark on all architectures|
|Affected versions||< 20.04.3-r2|
|Unaffected versions||>= 20.04.3-r2|
Ark is a graphical file compression/decompression utility with support for multiple formats.
KDE Ark did not fully verify symlinks contained within tar archives.
A remote attacker could entice a user to open a specially crafted tar archive using KDE Ark, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All KDE Ark users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-apps/ark-20.04.3-r2"
