CVE-2016-3191: Improper Restriction of Operations within the Bounds of a Memory Buffer

March 17, 2016 (updated January 5, 2018)

The compile_branch function in pcre_compile.c in PCRE and pcre2_compile.c in PCRE2 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.
