New medium priority openssl vulnerability: CVE-2022-2097

[post-svejk]

There is a new vulnerability being reported by azure/container-scan and trivy on our builds: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2097
Also flagged by Snyk at: https://snyk.io/test/docker/alpine:3.16.0

I cannot find any workarounds. Looks like the alpine package for openssl needs to be updated with fixed version of openssl first.

[MarekKosinski]

Is there any update on this issue?

@MarekKosinski updating affected packages in Dockerfile may help

FROM alpine
RUN apk add --update-cache \
        libcrypto1.1=1.1.1q-r0 \
        libssl1.1=1.1.1q-r0 && \
    rm -rf /var/cache/apk/*

FWIW, there is a new "edge" tag (20220715) available without this vuln. I tried the package upgrade suggested in #261 (comment), but couldn't make it work - because of package conflicts...

[kyberorg]

@erikgb actually switching from https to http repositories helps somehow

RUN sed -i 's,https,http,g' /etc/apk/repositories && \
    apk add --update-cache \
        libcrypto1.1=1.1.1q-r0 \
        libssl1.1=1.1.1q-r0 && \
    rm -rf /var/cache/apk/*

@kyberorg But doesn't that change make you vulnerable for MITM attacks, at least theoretically? Thanks for the info anyway!

FWIW, this might have been "medium" at some point but is now being reported as "high".

[SnazzyBootMan]

This does work but it is using the edge repository:

apk --no-cache add libcrypto1.1=1.1.1q-r0 libssl1.1=1.1.1q-r0 --repository=http://dl-cdn.alpinelinux.org/alpine/edge/community

Hi @MarekKosinski, Your suggestion fix my issue. Thanks.

The OS patch just dropped; the new image should be imminent

yes, the image should provide this latest version..

[keithmattix]

3.16.1 is available on DockerHub

[sshuklao]

@keithmattix still seeing the same issue in 3.16.1.

The scan results show that 1 ISSUE was found for the image.

@sshuklao I can confirm. Trivy gives same results.
Edge and 20220715 are shipping version 1.35.0-r18 and have 0 vulnerabilities.

[keithmattix]

@sshuklao That's a separate vuln. Compare the 3.16.0 snyk report with the 3.16.1 snyk report

[eli-darkly]

@sshuklao @keithmattix The one about awk, CVE-2022-30065, has an open issue here: #264

But it is still true that the 3.16.1 release notes are claiming to fix that vulnerability, and it doesn't seem to be fixed.

[keithmattix]

Ah, yep; I didn't check the CVE link. Looks like 3.16.1 is still affected
