A Denial of Service (DoS) condition has been discovered in GitLab CE/EE affecting all versions from 7.10 prior before 16.11.5, version 17.0 before 17.0.3, and 17.1 before 17.1.1. It is possible for an attacker to cause a denial of service using a crafted markdown page.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Gitlab Ubuntu esm-apps/xenial *

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.
