It's backed by a very fast entropy stage, provided by Huff0 and FSE library. It's a real-time compression scenario for zlib levels and has a better compression ratio.\r\n\r\nSecurity Fix(es):\r\n\r\nBeginning in v1.4.1 and prior to v1.4.9, due to an incomplete fix for CVE-2021-24031, the Zstandard command-line utility created output files with default permissions and restricted those permissions immediately afterwards. Output files could therefore momentarily be readable or writable to unintended parties.(CVE-2021-24032)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS","name":"zstd","purl":"pkg:rpm/openEuler/zstd\u0026distro=openEuler-20.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.5-1.oe1"}]}],"ecosystem_specific":{"aarch64":["zstd-1.4.5-1.oe1.aarch64.rpm","zstd-debuginfo-1.4.5-1.oe1.aarch64.rpm","zstd-debugsource-1.4.5-1.oe1.aarch64.rpm","zstd-devel-1.4.5-1.oe1.aarch64.rpm","zstd-debugsource-1.4.5-1.oe1.aarch64.rpm","zstd-debuginfo-1.4.5-1.oe1.aarch64.rpm","zstd-1.4.5-1.oe1.aarch64.rpm","zstd-devel-1.4.5-1.oe1.aarch64.rpm"],"noarch":["zstd-help-1.4.5-1.oe1.noarch.rpm","zstd-help-1.4.5-1.oe1.noarch.rpm"],"src":["zstd-1.4.5-1.oe1.src.rpm","zstd-1.4.5-1.oe1.src.rpm"],"x86_64":["zstd-debugsource-1.4.5-1.oe1.x86_64.rpm","zstd-devel-1.4.5-1.oe1.x86_64.rpm","zstd-1.4.5-1.oe1.x86_64.rpm","zstd-debuginfo-1.4.5-1.oe1.x86_64.rpm","zstd-debuginfo-1.4.5-1.oe1.x86_64.rpm","zstd-1.4.5-1.oe1.x86_64.rpm","zstd-debugsource-1.4.5-1.oe1.x86_64.rpm","zstd-devel-1.4.5-1.oe1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:20.03-LTS-SP1","name":"zstd","purl":"pkg:rpm/openEuler/zstd\u0026distro=openEuler-20.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.5-1.oe1"}]}],"ecosystem_specific":{"aarch64":["zstd-debugsource-1.4.5-1.oe1.aarch64.rpm","zstd-debuginfo-1.4.5-1.oe1.aarch64.rpm","zstd-1.4.5-1.oe1.aarch64.rpm","zstd-devel-1.4.5-1.oe1.aarch64.rpm"],"noarch":["zstd-help-1.4.5-1.oe1.noarch.rpm"],"src":["zstd-1.4.5-1.oe1.src.rpm"],"x86_64":["zstd-debuginfo-1.4.5-1.oe1.x86_64.rpm","zstd-1.4.5-1.oe1.x86_64.rpm","zstd-debugsource-1.4.5-1.oe1.x86_64.rpm","zstd-devel-1.4.5-1.oe1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2021-1094"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-24032"}],"database_specific":{"severity":"Critical"}}
