The pcre_compile2 function in pcre_compile.c in PCRE 8.38 mishandles the /((?:F?+(?:^(?®a+"){99}-))(?J)(?‘R’(?‘R’<((?‘RR’(?‘R’){97)?J)?J)(?‘R’(?‘R’){99|(:(?|(?‘R’)(\k’R’)|((?‘R’)))H’R’R)(H’R))))))/ pattern and related patterns with named subgroups, 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.
