A ReDoS based DoS vulnerability in the GlobalID <1.0.1 which could allow an attacker supplying a carefully crafted input can cause the regular expression engine to take an unexpected amount of time. All users running an affected release should either upgrade or use one of the workarounds immediately.
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.
Name | Vendor | Start Version | End Version |
---|---|---|---|
Globalid | Rubyonrails | 0.2.1 (including) | 1.0.1 (excluding) |
Red Hat Satellite 6.14 for RHEL 8 | RedHat | rubygem-globalid-0:1.1.0-1.el8sat | * |

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.
