+===============================
+
+Project curl Security Dismissal, August 26 2023 -
+[Permalink](https://curl.se/docs/CVE-2023-52071.html)
+
+VULNERABILITY
+-------------
+
+None. CVE-2023-52071 was filed and made public by an anonymous person due to
+incompetence or malice. We cannot say which and the distinction does not
+matter to us.
+
+The original description said:
+
+`tiny-curl-8_4_0`, `curl-8_4_0` and `curl-8_5_0` were discovered to contain an
+off-by-one out-of-bounds array index via the component `tool_cb_wrt`.
+
+INFO
+----
+
+CVE-2023-52071 was published on January 30 2024. Its existence was reported to
+us the same day.
+
+The CVE references a git commit that fixes an assert. The assert itself
+accesses a stack based buffer one byte out of boundary. This code is only
+included in debug builds and never in release-builds. Even in debug builds it
+is not a security problem.
+
+The referenced bug was introduced in [a
+commit](https://github.com/curl/curl/commit/af3f4e419b9f3397) done on April 4
+2023 (shipped in 8.3.0), later fixed again in [a
+commit](https://github.com/curl/curl/commit/73980f9ace6c7577e7) merged on
+September 13 2023 (shipped in 8.4.0).
+
+AFFECTED VERSIONS
+-----------------
+
+It does not affect any version. It is not a security problem. It was a bug
+that we fixed in September 2023.
+
+SOLUTION
+------------
+
+Relax. Use curl as usual.
+
+The curl security team will work on getting this CVE rejected.
+
+RECOMMENDATIONS
+--------------
+
+Do not blindly trust the CVE system. It is full of cracks and bogus reports
+such as CVE-2023-52071.
+
+TIMELINE
+--------
+
+This CVE was made public on January 30 2024. We were notified about it on
+January 30.
