pcre -- heap overflow vulnerability

Mitre reports:

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.
