Advisory Weakness Curation

protobuf-java has a potential Denial of Service issue ## Summary A potential Denial of Service issue in `protobuf-java` core and lite was discovered in the parsing procedure for binary and text format data. Input streams containing multiple instances of non-repeated embedded messages http://developers.google.com/protocol-buffers/docs/encoding#embedded 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. Reporter: OSS Fuzz https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=48771 Affected versions: This issue affects both the Java full and lite Protobuf runtimes, as well as Protobuf for Kotlin and JRuby, which themselves use the Java Protobuf runtime. ## Severity CVE-2022-3171 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-3171 Medium - CVSS Score: 5.7 (NOTE: there may be a delay in publication) ## Remediation and Mitigation Please update to the latest available versions of the following packages: protobuf-java (3.21.7, 3.20.3, 3.19.6, 3.16.3) protobuf-javalite (3.21.7, 3.20.3, 3.19.6, 3.16.3) protobuf-kotlin (3.21.7, 3.20.3, 3.19.6, 3.16.3) protobuf-kotlin-lite (3.21.7, 3.20.3, 3.19.6, 3.16.3) google-protobuf [JRuby gem only] (3.21.7, 3.20.3, 3.19.6)

Uncontrolled Resource Consumption 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.
