| description: |- |
| A bug in SAML authentication library can result in Denial of Service attacks. |
| |
| Attackers can craft a `deflate`-compressed request which will consume significantly more |
| memory during processing than the size of the original request. This may eventually lead |
| to memory exhaustion and the process being killed. |
