Description

Source-to-Image (S2I) is a tool for building reproducible container images. It produces ready-to-run images by injecting a user source into a container image and assembling a new container image. The new image incorporates the base image (the builder) and built source, and is ready to use with the "docker run" command. S2I supports incremental builds, which re-use previously downloaded dependencies, previously built artifacts, and more.

The following packages have been upgraded to a later upstream version: source-to-image (1.1.13). (BZ#1654243)

Security Fix(es):

• source-to-image: Improper path sanitization in ExtractTarStreamFromTarReader in tar/tar.go (CVE-2018-1102)
