CVE-2022-3171 is a resource-consumption vulnerability in the binary-data parsers of protobuf-java core and lite. Crafted inputs containing multiple instances of non-repeated embedded messages with repeated or unknown fields cause repeated conversions between mutable and immutable object representations. These conversions can produce prolonged garbage-collection pauses and denial of service. Affected releases precede the branch-specific fixes in versions 3.16.3, 3.19.6, 3.20.3, and 3.21.7. Some advisories additionally describe text-format parsing, although the CVE-specific description identifies binary-data parsing.
