Heap-based buffer overflow in the find_fixedlength function in pcre_compile.c in PCRE before 8.38 allows remote attackers to cause a denial of service (crash) or obtain sensitive information from heap memory and possibly bypass the ASLR protection mechanism via a crafted regular expression with an excess closing parenthesis.
