An integer overflow in the search_in_range function in regexec.c in
Oniguruma 6.x before 6.9.4_rc2 leads to an out-of-bounds read, in which the
offset of this read is under the control of an attacker. (This only affects
the 32-bit compiled version). Remote attackers can cause a
denial-of-service or information disclosure, or possibly have unspecified
other impact, via a crafted regular expression.
