Vulnerability Description
The compile_branch function in pcre_compile.c in PCRE 8.x before 8.39 and
pcre2_compile.c in PCRE2 before 10.22 mishandles patterns containing an
(*ACCEPT) substring in conjunction with nested parentheses, which allows
remote attackers to execute arbitrary code or cause a denial of service
(stack-based buffer overflow) via a crafted regular expression, as
demonstrated by a JavaScript RegExp object encountered by Konqueror, aka
ZDI-CAN-3542. (CVE-2016-3191)
Impact
This vulnerability may allow remote attackers to cause a denial-of-service
(DoS) attack or have other unspecified impacts via a crafted regular
expression.
