Description Sam Fowler 2018-10-15 06:07:12 UTC

The html package (aka x/net/html) through 2018-09-25 in Go mishandles <table><math><select><mi><select></table>, leading to an infinite loop during an html.Parse call because inSelectIM and inSelectInTableIM do not comply with a specification.

While the patch does look applicable, I am unable to reproduce this on RHEL.

Comment 3 Summer Long 2018-10-30 04:38:00 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 02:27:18 UTC

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