Vulnerability from fkie_nvd - Published: 2023-10-23 07:15 - Updated: 2025-08-25 02:09
Severity ?
Summary
When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A client could send new requests and resets, keeping the connection busy and open and causing the memory footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run out of memory before that.
This was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid Reset Exploit) with their own test client. During "normal" HTTP/2 use, the probability to hit this bug is very low. The kept memory would not become noticeable before the connection closes or times out.
Users are recommended to upgrade to version 2.4.58, which fixes the issue.

"value": "Cuando un cliente restablec\u00eda una secuencia HTTP/2 (trama RST), hab\u00eda una ventana de tiempo en la que los recursos de memoria de la solicitud no se recuperaban inmediatamente. En cambio, la desasignaci\u00f3n se aplaz\u00f3 hasta el cierre de la conexi\u00f3n. Un cliente podr\u00eda enviar nuevas solicitudes y reinicios, manteniendo la conexi\u00f3n ocupada y abierta y provocando que la huella de memoria siga creciendo. Al cerrar la conexi\u00f3n, se recuperaron todos los recursos, pero el proceso podr\u00eda quedarse sin memoria antes de eso. El periodista descubri\u00f3 esto durante la prueba de CVE-2023-44487 (HTTP/2 Rapid Reset Exploit) con su propio cliente de prueba. Durante el uso \"normal\" de HTTP/2, la probabilidad de encontrar este error es muy baja. La memoria guardada no se notar\u00e1 antes de que la conexi\u00f3n se cierre o se agote el tiempo de espera. Se recomienda a los usuarios actualizar a la versi\u00f3n 2.4.58, que soluciona el problema."
