+	  <p>The PCRE2 library is a set of C functions that implement regular
+	expression pattern matching.  In version 10.45, a heap-buffer-overflow
+	read vulnerability exists in the PCRE2 regular expression matching
+	engine, specifically within the handling of the (*scs:...) (Scan
+	SubString) verb when combined with (*ACCEPT) in src/pcre2_match.c.
+	This vulnerability may potentially lead to information disclosure
+	if the out-of-bounds data read during the memcmp affects the final
+	match result in a way observable by the attacker.</p>
