    CVE-2021-28831

    Summary: busybox security update

    Details: 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. Security Fix(es): decompress_gunzip.c in BusyBox through 1.32.1 mishandles the error bit on the huft_build result pointer, with a resultant invalid free or segmentation fault, via malformed gzip data.(CVE-2021-28831)
