Vulnerability Details

There is a possible regular expression based DoS vulnerability in Active Support. A specially crafted string passed to the underscore method can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability. The issue is patched in versions 6.1.7.1 and 7.0.4.1.
