Versions up to and including 2.5.12, 3.0.0-M1 through 3.12.2, and 3.13.0-M1 through 3.13.0-M6 are vulnerable to denial of service attacks though TLS sessions using fs2-io on the JVM using the fs2.io.net.tls package. When establishing a TLS session, if one side of the connection shuts down `write` while the peer side is awaiting more data to progress the TLS handshake, the peer side will spin loop on the socket read, fully utilizing a CPU. The CPU is consumed until the overall connection is closed, potentially shutting down a fs2-io powered server. This issue is fixed in versions  2.5.13, 3.12.1, and 3.13.0-M7."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":1.4}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-400"}]}],"references":[{"url":"https://github.com/typelevel/fs2/commit/46e2dc3abf994dcf3d0b804b2ddb3c10c04d4976","source":"security-advisories@github.com"},{"url":"https://github.com/typelevel/fs2/commit/5c6c4c6c1ef330f7e6b53661ecc63d5f5ba8885c","source":"security-advisories@github.com"},{"url":"https://github.com/typelevel/fs2/commit/edf0c4f2e660360d1c1a8c5377ce32294de89238","source":"security-advisories@github.com"},{"url":"https://github.com/typelevel/fs2/issues/3590","source":"security-advisories@github.com"},{"url":"https://github.com/typelevel/fs2/releases/tag/v3.12.2","source":"security-advisories@github.com"},{"url":"https://github.com/typelevel/fs2/releases/tag/v3.13.0-M7","source":"security-advisories@github.com"},{"url":"https://github.com/typelevel/fs2/security/advisories/GHSA-rrw2-px9j-qffj","source":"security-advisories@github.com"}]}}]}
