CVE-2007-4996

https://notcve.org/view.php?id=CVE-2007-4996

libpurple in Pidgin before 2.2.1 does not properly handle MSN nudge messages from users who are not on the receiver's buddy list, which allows remote attackers to cause a denial of service (crash) via a nudge message that triggers an access of "an invalid memory location." libpurple de Pidgin versiones anteriores a 2.2.1 no gestiona apropiadamente los mensajes personalizados de usuarios que no están en la lista de amigos del receptor, lo cual permite a atacantes remotos provocar una denegación de servicio (caída) mediante un mensaje personalizado que dispara un acceso de "ubicación inválida de memoria". • http://fedoranews.org/updates/FEDORA-2007-236.shtml http://secunia.com/advisories/27010 http://secunia.com/advisories/27088 http://www.pidgin.im/news/security/?id=23 http://www.securityfocus.com/archive/1/481402/100/0/threaded http://www.securityfocus.com/bid/25872 http://www.vupen.com/english/advisories/2007/3321 https://exchange.xforce.ibmcloud.com/vulnerabilities/36884 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A18261 •
