      <title>CVE-2022-1941 — Out of Memory issue in ProtocolBuffers for cpp and python</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2022-1941</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Google LLC protobuf-cpp, Google LLC protobuf-python, google protobuf-cpp, google protobuf-python&lt;/p&gt;
&lt;p&gt;A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can lead to out of memory failures. A specially crafted message with multiple key-value per elements creates parsing issues, and can lead to a Denial of Service against services receiving unsanitized input. We recommend upgrading to versions 3.18.3, 3.19.5, 3.20.2, 3.21.6 for protobuf-cpp and 3.18.3, 3.19.5, 3.20.2, 4.21.6 for protobuf-python. Versions for 3.16 and 3.17 are no longer updated.&lt;/p&gt;</description>
