Heap-based buffer overflow in PCRE 8.34 through 8.37 and PCRE2 10.10 allows remote attackers to execute arbitrary code via a crafted regular expression, as demonstrated by /^(?P=B)((?P=B)(?J:(?P<B>c)(?P<B>a(?P=B)))>WGXCREDITS)/, a different…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
