The pcre_compile2 function in PCRE before 8.37 allows context-dependent
attackers to compile incorrect code and cause a denial of service
(out-of-bounds read) via regular expression with a group containing both a
forward referencing subroutine call and a recursive back reference, as
demonstrated by “((?+1)(\1))/”.
