CVE-2025-58369

fs2 is a compositional, streaming I/O library for Scala. 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...

Improper Resource Shutdown or Release

Overview Affected versions of this package are vulnerable to Improper Resource Shutdown or Release after establishing a TLS session. An attacker can cause excessive CPU utilization by initiating a half-shutdown of the connection during the handshake, leading the peer to enter a spin loop on socke...

FS2 half-shutdown of socket during TLS handshake may result in spin loop on opposite side

Impact When establishing a TLS session using fs2-io on the JVM using the fs2.io.net.tls package, 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. This CPU...
