CVE-2021-32699
Asymmetric Resource Consumption (Amplification) in Docker containers created by Wings
Impact
### Impact All versions of Pterodactyl Wings preior to `1.4.4` are vulnerable to system resource exhaustion due to improper container process limits being defined. A malicious user can consume more resources than intended and cause downstream impacts to other clients on the same hardware, eventually causing the physical server to stop responding. ### Patches Users should upgrade to `1.4.4`. ### Workarounds There is no non-code based workaround for impacted versions of the software. Users running customized versions of this software can manually set a PID limit for containers created. ### For more information If you have any questions or comments about this advisory: * Contact us on [Discord](https://discord.gg/pterodactyl) * Email us at `dane ät pterodactyl dot io`
