Description Avinash Hanwate 2023-06-13 06:09:11 UTC

There exists an vulnerability causing an abort() to be called in gRPC.  The following headers cause gRPC's C++ implementation to abort() when called via http2: te: x (x != trailers) :scheme: x (x != http, https) grpclb_client_stats: x (x == anything) On top of sending one of those headers, a later header must be sent that gets the total header size past 8KB. We recommend upgrading past git commit 2485fa94bd8a723e5c977d55a3ce10b301b437f8 or v1.53 and above.

Initial analysis in https://bugzilla.redhat.com/show_bug.cgi?id=2214474#c2.

TLDR: It doesn’t look like the fix can be reliably backported to the packaged version; updating to a new enough version in Rawhide will require protobuf to be updated to 4.x (22.x/23.x), which is desirable but will probably impact a lot of packages; and updating to a new enough version in F38/F37/EPEL9 will not be possible due to the protobuf 4.x requirement and because the update would be ABI- and API-incompatible.

I’ve closed the flatbuffers bug because I verified that flatbuffers doesn’t bundle any of the grpc source files that were changed upstream to fix this issue. https://bugzilla.redhat.com/show_bug.cgi?id=2214475#c2
