In the Zstandard command-line utility prior to v1.4.1, output files were created with default permissions. Correct file permissions (matching the input) would only be set at completion time. Output files could therefore be readable or writable to unintended parties. En la utilidad Zstandard command-line versiones anteriores a v1.4.1, los archivos de salida se creaban con permisos predeterminados. Los permisos de archivo correctos (que coincidan con la entrada) solo se establecerán en el momento de la completación. • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=981404 https://github.com/facebook/zstd/issues/1630 https://www.facebook.com/security/advisories/cve-2021-24031 • CWE-276: Incorrect Default Permissions CWE-277: Insecure Inherited Permissions •

A race condition in the one-pass compression functions of Zstandard prior to version 1.3.8 could allow an attacker to write bytes out of bounds if an output buffer smaller than the recommended size was used. Una condición de carrera en las funciones de compresión de un paso (one-pass) de Zstandard anterior a versión 1.3.8, podría permitir a un atacante escribir bytes fuera de límites si es utilizado un búfer de salida más pequeño que el tamaño recomendado . • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00062.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00078.html https://github.com/facebook/zstd/pull/1404/commits/3e5cdf1b6a85843e991d7d10f6a2567c15580da0 https://usn.ubuntu.com/4108-1 https://www.facebook.com/security/advisories/cve-2019-11922 https://www.oracle.com/security-alerts/cpuoct2020.html • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
