Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|

Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
A DTLS Client could provide a Certificate that it doesn't posses the private key for and Pion DTLS wouldn't reject it.
This issue affects users that are using Client certificates only. The connection itself is still secure. The Certificate provided by clients can't be trusted when using a Pion DTLS server prior to v2.1.5
### Patches
Upgrade to Pion DTLS v2.1.5
### Workarounds
No workarounds available, upgrade to Pion DTLS v2.1.5
