3. 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)
