Medium security issues in dependencies
sseide opened this issue · comments
Hello,
different scanner pick up warnings in remco with two different libraries used. As i do not understand go and its dependency system it is hard to resolve for me. Especially i do not know how to get a real dependency tree to see what needs fixing...
Snyk Security scanner (much more helpful as it shows dependencies):
✗ Medium severity vulnerability found in gopkg.in/yaml.v2
Description: Denial of Service (DoS)
Info: https://snyk.io/vuln/SNYK-GOLANG-GOPKGINYAMLV2-1083943
Introduced through: github.com/HeavyHorst/easykv/file@1.2.5, github.com/ghodss/yaml@1.0.0
From: github.com/HeavyHorst/easykv/file@1.2.5 > gopkg.in/yaml.v2@2.2.5
From: github.com/ghodss/yaml@1.0.0 > gopkg.in/yaml.v2@2.2.5
Fixed in: 2.2.8
At least for your own package easykv an update is available in Github but that is not released so far (1.2.5 is latest). Therefor creating a new release 1.2.6 and using it would help partially?
Anchore Security scanner (not that helpful):

NAME INSTALLED FIXED-IN VULNERABILITY SEVERITY
golang.org/x/crypto v0.0.0-20190701094942-4def268fd1a4 0.0.0-20200220183623-bac4c82f6975 GHSA-ffhg-7mh4-33c4 Medium
gopkg.in/yaml.v2 v2.2.5 2.2.8 GHSA-wxc4-f4m6-wwqv Medium
yaml.v2 is the same as above, but new golang.org/x/crypto uses way to old versions in go.sum. But here i do not know what dependency needs an update...
Side note:
your Makefile help mentions "make get-deps" to rebuild vendor directory but it seems the correct command is "make vendor". Right?
Just trying to understand go...
Thanks for the scan!
I've updated easyKV, replaced ghodss/yaml with the kubernetes fork (sigs.k8s.io/yaml) and explicitly set the gopkg.in/yaml.v2 version to 2.4.0 in the go.mod file
Could you rerun your scan plz?
Hi,
thanks for the fast response. With the updated code the snyk.io and Anchore scanner are fine.
And checked afterwards with Sonartype OSSIndex base one too now ("nancy" for go lang - https://github.com/sonatype-nexus-community/nancy) which brought up something else with "etcd". But as i read the descriptions at least the first and third one for server-side code, second one i do not really know if client side code is affected too.
But due to the other updates the etcd api and client are on version 3.5.1 according to go.sum now while the main etcd lib (the one the warning is for) stays on 3.3.17. I do not know if there might be a problem too mixing different version...
remco/cmd/remco$ go list -json -deps | nancy sleuth
Checking for updates...
Already up-to-date.

┃ Description ┃ In etcd before versions 3.3.23 and 3.4.10, the etcd gateway is a simple TCP ┃
┃ ┃ proxy to allow for basic service discovery and access. However, it is ┃
┃ ┃ possible to include the gateway address as an endpoint. This results in a ┃

┃ Description ┃ In ectd before versions 3.4.10 and 3.3.23, gateway TLS authentication is ┃
┃ ┃ only applied to endpoints detected in DNS SRV records. When starting a ┃
┃ ┃ gateway, TLS authentication will only be attempted on endpoints identified ┃

Thanks again!
I updated the etcd deps.
Many thanks, now everything green again.
It would be really nice when you may release a new version after the PR is merged.
Sure, i releases v0.12.2
