Name of the Vulnerable Software and Affected Versions PCRE versions prior to 8.36

Description The issue is related to the handling of certain internal recursive back references in regular expressions. Specifically, patterns like /(((a2)|(a*)g<-1>))*/ can cause a denial of service (segmentation fault) or possibly have other unspecified impacts when encountered by affected software. This can be triggered by a crafted regular expression, for example, through a JavaScript RegExp object.
