CVE-2015-5073

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.67%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
