CVE-2021-24032 is fixed in 2 products on 1 platform, first by libzstd1 1.3.3+dfsg-2ubuntu1.2, released February 19, 2021. It is not reported as exploited. Patch Radar priority: Routine.
Beginning in v1.4.1 and prior to v1.4.9, due to an incomplete fix forCVE-2021-24031, the Zstandard command-line utility created output fileswith default permissions and restricted those permissions immediatelyafterwards. Output files could therefore momentarily be readable orwritable to unintended parties.
