CVE-2015-8392: Buffer Overflow
First published: Wed Dec 02 2015(Updated: )
PCRE before 8.38 mishandles certain instances of the (?| substring, which allows remote attackers to cause a denial of service (unintended recursion and buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror, a related issue to CVE-2015-8384 and CVE-2015-8395.
