CVE-2021-21293 Unbounded connection acceptance leads to file handle exhaustion

blaze is a Scala library for building asynchronous pipelines, with a focus on network IO. All servers running blaze-core before version 0.14.15 are affected by a vulnerability in which unbounded connection acceptance leads to file handle exhaustion. Blaze, accepts connections unconditionally on a...

CVE-2021-21293

CVE-2021-21293 concerns blaze-core prior to 0.14.15, where unbounded acceptance of new connections on a dedicated thread pool can exhaust file handles and degrade services. Affected component is blaze-core (used by http4s-blaze-server) with unbounded queues after accept. The fix in 0.14.15 adds a...
