xmldom: End-tag Whitespace-Trim Regex ReDoS — quadratic backtracking in the 0.8.x end-tag parser

Summary On the @xmldom/xmldom 0.8.x line, parsing an XML end tag whose name is followed by a long run of whitespace and then a non-whitespace character triggers quadratic-time regular-expression backtracking ReDoS, so a single small crafted end tag stalls the Node.js event loop. It is reachable...

GHSA-2WM5-Q62R-HMRV Colord: Slow rejection of oversized malformed color strings

Impact colord's CSS color string matchers described a number as +-?\d.?\d+. In that form \d and \d+ can match the same digits, so a run of n digits can be divided between them in On² ways, and rejecting an input retries every division. Parsing is synchronous and uninterruptible, so a long...
