CVE-2015-8381 (retired)

Priority
Description
The compile_regex function in pcre_compile.c in PCRE before 8.38 and
pcre2_compile.c in PCRE2 before 10.2x mishandles the
/(?J:(?|(:(?|(?'R')(\k'R')|((?'R')))H'Rk'Rf)|s(?'R'))))/ and
/(?J:(?|(:(?|(?'R')(\z(?|(?'R')(\k'R')|((?'R')))k'R')|((?'R')))H'Ak'Rf)|s(?'R')))/
patterns, and related patterns with certain group references, 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.
Notes
