GHSA-6WVC-6PWW-QR4R
Vulnerability from github – Published: 2022-07-11 21:06 – Updated: 2022-07-11 21:06Impact
A large response received by the viaduct WSClient can cause a DoS from memory exhaustion. The entire body of the response is being read into memory which could allow an attacker to send a request that returns a response with a large body.
The consequence of the exhaustion is that the process which invokes a WSClient will be in a denial of service. It will be affected If users which are authenticated to the edge side and connect from the edge side to cloudhub through WebSocket protocol.
Patches
This bug has been fixed in Kubeedge 1.11.1, 1.10.2, 1.9.4. Users should update to these versions to resolve the issue.
Workarounds
