CVE-2022-3510 Information

Description

A parsing issue similar to CVE-2022-3171 but with Message-Type Extensions in protobuf-java core and lite versions prior to 3.21.7 3.20.3 3.19.6 and 3.16.3 can lead to a denial of service attack. 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.
