The user could pass more than 1 MB of data in the HTTP request to the processing functions, which will be decompressed server-side using the Deflate algorithm. Therefore, after repeating the same request multiple times, it is possible to achieve a reliable crash since the operating system kills the process.\n\n\n## Affected packages\n\n- `github.com/crewjam/saml < 0.4.13`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/crewjam/saml 0.4.13`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
