| summary: |- |
| Denial of service via deflate decompression bomb in |
| github.com/russellhaering/gosaml2 |
| 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. |
