Comment 1 David Walser 2021-06-22 00:35:01 CEST

Advisory:
========================

Updated qtwebsockets5 packages fix security vulnerability:

In Qt through 5.14.1, the WebSocket implementation accepts up to 2GB for frames
and 2GB for messages. Smaller limits cannot be configured. This makes it easier
for attackers to cause a denial of service (memory consumption)
(CVE-2018-21035).

Comment 2 Herman Viaene 2021-06-22 10:58:37 CEST

MGA7-64 Plasma on Lenovo B50
No installation issues.
This seems to me like ddeveloper's library, confirmed by
# urpmq --whatrequires qtwebsockets5
lib64qt5websockets-devel
qtwebsockets5
and
# urpmq --whatrequires-recursive qtwebsockets5
lib64nextcloud-client-devel
lib64qt5websockets-devel
qtwebsockets5

So OK'ing on clean install.
