Share on: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.
