What is CVE-2018-17848?

The Go html package (x/net/html) prior to September 25, 2018, exhibits improper handling of specific math template tags, causing unexpected runtime behavior. When processing HTML parse calls involving these tags, the insertionModeStack encounters an error, leading to a 'panic: runtime error' due to an index out of range issue in the node.go file. This vulnerability can disrupt applications that depend on the accurate rendering of mathematical expressions in HTML documents.
