Alpine: multiple buildah packages: security update to 1.23.4-r0

medium Tenable Self-Hosted Container Security Plugin ID 403723

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package
 in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version
 1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential
 memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an
 instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`;
 not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our
 middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`.
 client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including
 removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected
 promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method
 given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow
 a limited set of methods. (CVE-2022-21698)

 - A flaw was found in buildah where containers were incorrectly started with non-empty default permissions.
 A bug was found in Moby (Docker Engine) where containers were incorrectly started with non-empty
 inheritable Linux process capabilities, enabling an attacker with access to programs with inheritable file
 capabilities to elevate those capabilities to the permitted set when execve(2) runs. This has the
 potential to impact confidentiality and integrity. (CVE-2022-27651)
