An update for busybox is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1449 Final 1.0 1.0 2021-12-03 Initial 2021-12-03 2021-12-03 openEuler SA Tool V1.0 2021-12-03 busybox security update An update for busybox is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. It provides a fairly complete environment for any small or embedded system.
