An integer overflow vulnerability exists with the length of websocket frames received via a websocket connection. An attacker could use this flaw to cause a denial of service attack on an HTTP Server allowing websocket connections.
7.5 (High)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2021:2920
A null pointer dereference vulnerability was found in golang. When using the library's ssh server without specifying an option for GSSAPIWithMICConfig, it is possible for an attacker to craft an ssh client connection using the `gssapi-with-mic` authentication method and cause the server to panic resulting in a denial of service. The highest threat from this vulnerability is to system availability.
7.5 (High)
Vendor Fix

https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2021:2920
A flaw detected in golang: crypto/elliptic, in which P-224 keys as generated can return incorrect inputs, reducing the strength of the cryptography. The highest threat from this vulnerability is confidentiality and integrity.
6.5 (Medium)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2021:2920
A flaw was found in github.com/gogo/protobuf before 1.3.2 that allows an out-of-bounds access when unmarshalling certain protobuf objects. This flaw allows a remote attacker to send crafted protobuf messages, causing panic and resulting in a denial of service. The highest threat from this vulnerability is to availability.
8.6 (High)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2021:2920
A flaw was found in github.com/ulikunitz/xz. The function readUvarint may not terminate a loop what could lead to denial of service (DoS).
