While no practical attack on s2n-tls has been demonstrated, this causes a small timing difference which could theoretically be used as described in the Marvin Attack [1].\n\nWe would like to thank Hubert Kario [2] for reporting this issue.\n\n\n### Impact\n\nThe extent of this issue is a timing difference. No practical attack on s2n-tls has been demonstrated.\n\nThis issue affects server applications that permit RSA key exchange. Applications that use the default, built-in blinding feature or properly implement self-service blinding are not affected.\n\nImpacted versions: <= v1.4.15.\n\n\n### Patches\n\nThe patch is included in v1.4.16 [3].\n\n### Workarounds\n\nApplications can work around this issue by using an s2n-tls security policy that disallows RSA key exchange.\n\nIf you have any questions or comments about this advisory we ask that you contact AWS/Amazon Security via our vulnerability reporting page [4] or directly via email to [aws-security@amazon.com](mailto:aws-security@amazon.com).
