CVE-2017-7245
Stack-based buffer overflow in the pcre32_copy_substring function in pcre_get.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a denial of service (WRITE of size 4) or possibly have unspecified other impact via a crafted file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
