CVE-2016-1283 (retired)

Priority
Description
The pcre_compile2 function in pcre_compile.c in PCRE 8.38 mishandles the
/((?:F?+(?:^(?(R)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.
