CVE-2015-8386 – pcre: Buffer overflow caused by lookbehind assertion (8.38/6)

https://notcve.org/view.php?id=CVE-2015-8386

PCRE before 8.38 mishandles the interaction of lookbehind assertions and mutually recursive subpatterns, 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. PCRE en versiones anteriores a 8.38 no maneja correctamente la interacción de aserciones lookbehind y de subpatrones mutuamente recursivos, lo que permite a atacantes remotos causar una denegación de servicio (desbordamiento de buffer) o posiblemente tener otro impacto no especificado a través de una expresión regular manipulada, según lo demostrado por un objeto JavaScript RegExp encontrado por Konqueror. • http://lists.fedoraproject.org/pipermail/package-announce/2016-January/174931.html http://rhn.redhat.com/errata/RHSA-2016-1025.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://vcs.pcre.org/pcre/code/trunk/ChangeLog?view=markup http://www-01.ibm.com/support/docview.wss?uid=isg3T1023886 http://www.openwall.com/lists/oss-security/2015/11/29/1 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/82990 https:&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
