CVE-2024-7246  (opens in a new tab)

How to fix?

There is no fixed version for Debian:unstable grpc.

NVD Description

Note: Versions mentioned in the description apply only to the upstream grpc package and not the grpc package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

It's possible for a gRPC client communicating with a HTTP/2 proxy to poison the HPACK table between the proxy and the backend such that other clients see failed requests. It's also possible to use this vulnerability to leak other clients HTTP header keys, but not values.

This occurs because the error status for a misencoded header is not cleared between header reads, resulting in subsequent (incrementally indexed) added headers in the first request being poisoned until cleared from the HPACK table.

Please update to a fixed version of gRPC as soon as possible. This bug has been fixed in 1.58.3, 1.59.5, 1.60.2, 1.61.3, 1.62.3, 1.63.2, 1.64.3, 1.65.4.
