Erick Erickson commented on SOLR-14844:
---------------------------------------
[~samuelgmartinez] That'd be great (if you supplied a patch). I'm much more
comfortable now that you have an explanation. I'm not clear on why this only
fails in 8x and not master, but that's just my confusion.
How do you want to proceed? If you just attach a patch file, I can put it in
this upgrade or we can have a separate patch...
Let me know and thanks!
> Upgrade Jetty to 9.4.32.v20200930
> ---------------------------------
>
> Key: SOLR-14844
> URL: https://issues.apache.org/jira/browse/SOLR-14844
> Project: Solr
> Issue Type: Improvement
> Affects Versions: 8.6
> Reporter: Cassandra Targett
> Assignee: Erick Erickson
> Priority: Major
>
> A CVE was found in Jetty 9.4.27-9.4.29 that has some security scanning tools
> raising red flags
> ([https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-17638]).
> Here's the Jetty issue:
> [https://bugs.eclipse.org/bugs/show_bug.cgi?id=564984]. It's fixed in
> 9.4.30+, so we should upgrade to that for 8.7
> -It has a simple mitigation (raise Jetty's responseHeaderSize to higher than
> requestHeaderSize), but I don't know how Solr uses Jetty well enough to a)
> know if this problem is even exploitable in Solr, or b) if the workaround
> suggested is even possible in Solr.-
> In normal Solr installs, w/o jetty optimizations, this issue is largely
> mitigated in 8.6.3: see SOLR-14896 (and linked bug fixes) for details.
