Description
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary error in the compile_branch function. A remote attacker can create a regular expression with a group containing a forward reference repeated a large number of times within a repeated outer group that has a zero minimum quantifier, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
Remediation
