CyberRota Analysis
AI-GeneratedThe vulnerability affects Colord versions prior to 2.9.4, specifically in the synchronous CSS color string matchers, which can be exploited by attackers supplying unbounded color strings. This can lead to denial-of-service conditions by blocking the processing thread with a large payload. Users of Colord, particularly those handling user-generated color inputs, should prioritize upgrading to version 2.9.4 to mitigate this risk.

Original NVD Description
Colord is a tiny yet powerful tool for high-performance color manipulations and conversions. Prior to 2.9.4, synchronous CSS color string matchers in src/colorModels/rgbString.ts, src/colorModels/hslString.ts, src/colorModels/hwbString.ts, src/colorModels/lchString.ts, and src/colorModels/cmykString.ts use the ambiguous numeric regular expression ([+-]?\d*.?\d+), allowing the same digits to be divided between overlapping quantifiers in quadratically many ways when malformed input is rejected. An attacker who can supply an unbounded color string to colord(), getFormat(), isEqual(), mix(), or contrast(), including through a request body, JSON field, or uploaded stylesheet, can block the processing thread with a multi-kilobyte payload. The affected matchers are parseRgbaString, parseHslaString, parseHwbaString, parseLchaString, and parseCmykaString. This issue is fixed in version 2.9.4.
