Infinite Loop Vulnerability in Go's HTML Package Affecting Multiple Versions

CVE-2018-17846

What is CVE-2018-17846?

The HTML package (x/net/html) in Go prior to September 25, 2018, is vulnerable to an infinite loop issue. This arises from improper handling of nested table and select elements during HTML parsing. Specifically, the inSelectIM and inSelectInTableIM state machines do not comply with established parsing specifications, leading to potential denial of service through extensive resource consumption when specific HTML structures are fed into the parsing mechanism.
