CVE-2022-3510 Published on December 12, 2022
Parsing issue in protobuf message-type extension

Inputs containing multiple instances of non-repeated embedded messages with repeated or unknown fields causes objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses. We recommend updating to the versions mentioned above.
