The compile_branch function in PCRE before 8.37 allows context-dependent
attackers to compile incorrect code, cause a denial of service
(out-of-bounds heap read and crash), or possibly have other unspecified
impact via 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.
