In PCRE 8.41, the OP_KETRMAX feature in the match function in pcre_exec.c allows stack exhaustion (uncontrolled recursion) when processing a crafted regular expression.
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
