  "summary" : "The Eclipse Jetty Server Artifact has a Gzip request memory leak ",
  "details" : "### Description (as reported)\n\nThere is a memory leak when using `GzipHandler` in jetty-12.0.30 that can cause off-heap OOMs. This can be used for DoS attacks so I'm reporting this as a vulnerability.\n\nThe leak is created by requests where the request is inflated (`Content-Encoding: gzip`) and the response is not deflated (no `Accept-Encoding: gzip`). In these conditions, a new inflator will be created by `GzipRequest` and never released back into `GzipRequest.__inflaterPool` because `gzipRequest.destory()` is not called.\n\nIn heap dumps one can see thousands of `java.util.zip.Inflator` objects, which use both Java heaps and native memory. Leaking native memory causes of off-heap OOMs.\n\nCode path in `GzipHandler.handle()`:\n1. Line 601: `GzipRequest` is created when request inflation is needed.\n2. Lines 611-616: The callback is only wrapped in `GzipResponseAndCallback` when both inflation and deflation are needed.\n3. Lines 619-625: If the handler accepts the request (returns true), `gzipRequest.destroy()` is only called in the \"request not accepted\" path (returns false)\n\nWhen deflation is needed, `GzipResponseAndCallback` (lines 102 and 116) properly calls `gzipRequest.destroy()` in its `succeeded()` and `failed()` methods. But this wrapper is only created when deflation is needed.\n\nPossible fix:\nThe callback should be wrapped whenever a `GzipRequest` is created, not just when deflation is needed. This ensures `gzipRequest.destroy()` is always called when the request completes.\n\n\n### Impact\nThe leak causes the JVM to crash with OOME.\n\n### Patches\nNo patches yet.\n\n### Workarounds\nDisable `GzipHandler`.\n\n### References\nhttps://github.com/jetty/jetty.project/issues/14260\n\nhttps://gitlab.eclipse.org/security/cve-assignment/-/issues/79",
