CVE-ID : CVE-2020-16121
Package : packagekit
Type : information disclosure
Remote : No
Link : https://security.archlinux.org/AVG-1260

Summary

The package packagekit before version 1.2.3-1 is vulnerable to

Resolution

Upgrade to 1.2.3-1.

pacman -Syu “packagekit>=1.2.3-1”

The problem has been fixed upstream in version 1.2.3.

Workaround

Description

The InstallFiles, GetFilesLocal and GetDetailsLocal methods of the DBus
interface to PackageKit <= 1.1.13 access files before checking for

of any file on the system.

Impact

on the system.
