  • Embedded HAProxy version: 2.0.30
  • GitHub release: https://github.com/jcmoraisjr/haproxy-ingress/releases/tag/v0.10.15

Release notes (r15)

Warning: due to the update of some old dependencies with vulnerability, the Go version used to compile this release was updated from 1.13 to 1.17.

This release fixes the following issues:

  • Service resources accept annotations just like ingress ones. However services annotated with path scoped annotations, like haproxy-ingress.github.io/cors-enable and haproxy-ingress.github.io/auth-url, were applying the configuration to just one of the paths pointing the service. So, considering domain.local/path1 and domain.local/path2 pointing to svc1, an annotation added to svc1 would only be applied to one of the paths.
  • Known operating system vulnerabilities were not being fixed or updated during the creation of the controller container image.

Dependencies:

  • Embedded HAProxy version was updated from 2.0.28 to 2.0.30.
  • Go updated from 1.13.15 to 1.17.13.

Fixes and improvements (r15)

New features and improvements since v0.10.14:

  • Add apk upgrade on container building #941 (jcmoraisjr)
  • Fix path scoped annotation on service resources #984 (jcmoraisjr)
  • update embedded haproxy from 2.0.28 to 2.0.30 4cf4333 (Joao Morais)
  • update go from 1.13.15 to 1.17.13 and dependencies 2b04c6a (Joao Morais)

v0.10.14

  • Image (Quay): quay.io/jcmoraisjr/haproxy-ingress:v0.10.14
  • Image (Docker Hub): jcmoraisjr/haproxy-ingress:v0.10.14
  • Embedded HAProxy version: 2.0.28
  • GitHub release: https://github.com/jcmoraisjr/haproxy-ingress/releases/tag/v0.10.14

Release notes (r14)

This release fixes backend configuration snippets with blank lines. Such blank lines were being rejected due to a wrong parsing of a missing --disable-config-keywords command-line option.

Also, the embedded HAProxy version was updated from 2.0.26 to 2.0.28.

Release notes (r11)

This release updates the embedded HAProxy version from 2.0.24 to 2.0.25, which fixes a HAProxy's vulnerability with the Content-Length HTTP header. CVE-2021-40346 was assigned. The following announce from the HAProxy's mailing list has the details and possible workaround: https://www.mail-archive.com/haproxy@formilux.org/msg41114.html

Also, a misconfigured oauth (e.g. a missing service name) was allowing requests to reach the backend instead of deny the requests.

Fixes and improvements (r11)

Fixes and improvements since v0.10.10:

  • always deny requests if oauth is misconfigured 1ff88ec (Joao Morais)

Release notes (r10)

This release updates the embedded HAProxy version from 2.0.22 to 2.0.24, which fixes some HAProxy's HTTP/2 vulnerabilities. A malicious request can abuse the H2 :method pseudo-header to forge malformed HTTP/1 requests, which can be accepted by some vulnerable backend servers. The following announce from the HAProxy's mailing list has the details: https://www.mail-archive.com/haproxy@formilux.org/msg41041.html

Fixes and improvements (r10)

  • GitHub release: https://github.com/jcmoraisjr/haproxy-ingress/releases/tag/v0.10.9

Release notes (r9)

This release adds some security options: --disable-external-name can be used to not allow backend server discovery using an external domain; --disable-config-keywords can be used to partially or completely disable configuration snippets via ingress or service annotations.

Also, a warning will be emitted if the configured global ConfigMap does not exist.

There is no urge to update, except if some of the new options seem useful.
