Description Sam Fowler 2018-10-15 06:10:02 UTC

The html package (aka x/net/html) through 2018-09-25 in Go mishandles <svg><template><desc><t><svg></template>, leading to a "panic: runtime error" (index out of range) in (*nodeStack).pop in node.go, called from (*parser).clearActiveFormattingElements, during an html.Parse call.

Comment 2 Scott Gayou 2018-10-16 21:54:44 UTC

No upstream fix found yet, but this is not reproducible on RHEL7. My guess is this is similar to the other template related flaws.

See https://bugzilla.redhat.com/show_bug.cgi?id=1633022 as an example.

Not affected / not reproducible on our released version.

Comment 3 Summer Long 2018-10-30 04:37:36 UTC

OpenStack OpTools 8 and 9 grafana versions do not include net/html, which has the flawed code, setting these to NotAffected.

Comment 8 Joshua Padman 2019-08-21 02:27:06 UTC

Kompose was in DevTools as part of devsuite. Devsuite is now retired (https://developers.redhat.com/products/devsuite/overview/)

Comment 9 Riccardo Schirone 2019-11-27 08:19:18 UTC
