The html package (aka x/net/html) through 2018-09-17 in Go mishandles <math><template><mo><template>, leading to a "panic: runtime error" in parseCurrentToken in parse.go during an html.Parse call.

Comment 4 Scott Gayou 2018-10-16 21:02:29 UTC 
Version packaged by RHEL (around 2014) does not seem to include the template functionality. Vulnerable behavior looks to have been introduced here, in 2017: https://github.com/golang/net/commit/500e7a4f953ddaf55d316b4d3adc516aa0379622

Reproducer does not trigger an exception.
Comment 5 Summer Long 2018-10-19 06:19:09 UTC 
OpenStack OpTools 8/9 grafana versions do not include net/html, which includes the flawed code. OpenStack OpTools golang-googecode-net 9 does have the code, but this version does not support templates (which is needed for flaw exploitation).
