Integer signedness error in Opera before 8.54 allows remote attackers to execute arbitrary code via long values in a stylesheet attribute, which pass a length check. NOTE: a sign extension problem makes the attack easier with shorter strings. Error de entero sin signo en Opera en versiones anteriores a 8.54 permite a atacantes remotos ejecutar código arbitrario a través de valores largos en un atributo de la hoja de estilos, lo que pasa una verificación de longitud. NOTA: un problema de extensión de signo hace el ataque más fácil con cadenas cortas. • https://www.exploit-db.com/exploits/27641 http://lists.suse.com/archive/suse-security-announce/2006-May/0004.html http://marc.info/?l=full-disclosure&m=114493114031891&w=2 http://secunia.com/advisories/20117 http://security.gentoo.org/glsa/glsa-200606-01.xml http://securitytracker.com/id?1015912 http://www.opera.com/docs/changelogs/windows/854 http://www.sec-consult.com/259.html http://www.securityfocus.com/archive/1/430876/100/0/threaded http://www.securityfocus.c • CWE-189: Numeric Errors •
