      <title>CVE-2022-3510 — Parsing issue in protobuf message-type extension</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-3510</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Google ProtocolBuffers&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
