Overview
Affected versions of this package are vulnerable to Out-of-bounds Read via the regular expression matching engine due to missing boundary restoration in SCS. An attacker can cause a heap buffer over-read and potentially disclose sensitive information or cause a denial of service by supplying specially crafted regular expressions containing certain patterns such as a backreference (e.g., \2).
Note:
An attacker-controlled regex pattern is required, and it cannot be triggered by providing crafted subject (match) text. The (*ACCEPT) and (*scs:) pattern features must be used together.
