+Subject: [PATCH] CVE-2022-41741, CVE-2022-41742
+
+Upstream-Status: Backport [https://github.com/nginx/nginx/commit/6b022a5556af22b6e18532e547a6ae46b0d8c6ea]
+CVE: CVE-2022-41741, CVE-2022-41742
+Signed-off-by: Hitendra Prajapati <hprajapati@mvista.com>
+
+Mp4: disabled duplicate atoms.
+
+Most atoms should not appear more than once in a container.  Previously,
+this was not enforced by the module, which could result in worker process
+crash, memory corruption and disclosure.
