Image Builder is a service for building customized OS artifacts, such as VM images and OSTree commits, that uses osbuild under the hood.

Security Fix(es):

  • golang: math/big: decoding big.Float and big.Rat types can panic if the encoded message is too short, potentially allowing a denial of service (CVE-2022-32189)
