    CVE-2022-3171

    Published: 12 Oct 2022Last Modified: 12 Aug 2026

    Summary: Memory handling vulnerability in ProtocolBuffers Java core and lite

    Details: A parsing issue with binary data 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.
