Alpine: multiple sddm packages: security update to 0.19.0-r0

medium Tenable Self-Hosted Container Security Plugin ID 407139

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An issue was discovered in SDDM before 0.19.0. It incorrectly starts the X server in a way that - for a
 short time period - allows local unprivileged users to create a connection to the X server without
 providing proper authentication. A local attacker can thus access X server display contents and, for
 example, intercept keystrokes or access the clipboard. This is caused by a race condition during
 Xauthority file creation. (CVE-2020-28049)
