The pcre_exec function in pcre_exec.c in PCRE before 8.38 mishandles a //
pattern with a \01 string, which allows remote attackers to cause a denial
of service (heap-based buffer overflow) or possibly have unspecified other
impact via a crafted regular expression, as demonstrated by a JavaScript
RegExp object encountered by Konqueror.
