Vulnerability from fkie_nvd - Published: 2015-12-02 01:59 - Updated: 2026-06-17 00:23
Severity
Summary
PCRE before 8.36 mishandles the /((?(R)a|(?1)))+/ pattern and related patterns with certain recursion, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
