CVE-2022-3171

MEDIUM

Google Protobuf < 3.21.7, 3.20.3, 3.19.6, 3.16.3 - Denial of Service via Binary Data Parsing

Title source: llm
STIX 2.1

Description

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.
