      <title>CVE-2021-22570 — Nullptr Dereference in Protobuf</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2021-22570</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Google LLC Protobuf&lt;/p&gt;
&lt;p&gt;Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file&amp;#39;s name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater.&lt;/p&gt;</description>

      <title>Withdrawn: GHSA-77rm-9x9h-xj3g — Withdrawn Advisory: NULL Pointer Dereference in Protocol Buffers</title>
      <link>https://vulnerability.circl.lu/vuln/ghsa-77rm-9x9h-xj3g</link>
      <description>&lt;p&gt;&lt;strong&gt;Withdrawn by the publisher.&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; NuGet: Google.Protobuf, Packagist: google/protobuf, Maven: com.google.protobuf:protobuf-java, Go: github.com/protocolbuffers/protobuf, PyPI: protobuf&lt;/p&gt;
&lt;p&gt;### Withdrawn Advisory&lt;/p&gt;
&lt;p&gt;This advisory has been withdrawn because the protobuf vulnerability comes from the compiler rather that the code. This link is maintained to preserve external references.&lt;/p&gt;
