Description Sam Fowler 2018-10-15 02:14:49 EDT 
The html package (aka x/net/html) through 2018-09-25 in Go mishandles <math><template><mn><b></template>, leading to a "panic: runtime error" (index out of range) in (*insertionModeStack).pop in node.go, called from inHeadIM, during an html.Parse call.

Comment 2 Scott Gayou 2018-10-16 17:58:04 EDT 
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 00:37:27 EDT 
OpenStack OpTools 8 and 9 grafana versions do not include net/html, which has the flawed code, setting these to NotAffected.
