Excessive CPU usage
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | github.com/pomerium/pomerium | < 0.14.8 | 0.14.8 |

Details
As written in the advisory (Markdown source, shown as plain text).
Envoy, which Pomerium is based on, incorrectly handles resetting of HTTP/2 streams with excessive complexity. This can lead to high CPU utilization when a large number of streams are reset.
### Impact
This can result in a DoS condition.
### Patches
Pomerium versions 0.14.8 and 0.15.1 contain an upgraded envoy binary with this vulnerability patched.
### Workarounds
N/A
