Ubuntu

@adobe/css-tools versions 4.3.1 and earlier are affected by an Improper Input Validation vulnerability that could result in a denial of service while attempting to parse CSS.

Weakness

The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.

Extended Description

	  Attackers can create crafted inputs that
	  intentionally cause the regular expression to use
	  excessive backtracking in a way that causes the CPU
	  consumption to spike.
