pcre: buffer overflow caused by named forward reference to duplicate group number (8.38/30)
Published Dec 2, 2015
7.5
HIGHCVSS 2.0
EPSS 5.62%
Description
PCRE before 8.38 mishandles the /(?|(\k'Pm')|(?'Pm'))/ pattern and related patterns with certain forward references, which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
