CVSS: 4.3EPSS: 5%CPEs: 48EXPL: 1CVE-2011-3594 – libpurple: invalid UTF-8 string handling in SILC messages
https://notcve.org/view.php?id=CVE-2011-3594
The g_markup_escape_text function in the SILC protocol plug-in in libpurple 2.10.0 and earlier, as used in Pidgin and possibly other products, allows remote attackers to cause a denial of service (crash) via invalid UTF-8 sequences that trigger use of invalid pointers and an out-of-bounds read, related to interactions with certain versions of glib2. La función g_markup_escape_text en el complemento de protocolo SILC en libpurple v2.10.0 y anteriores, como se usa en Pidgin y posiblemente en otros productos, permite a atacantes remotos provocar una denegación de servicio (caída) a través de secuencias UTF-8 inválidas que disparan el uso de punteros no válidos y lectura fuera de los límites, relacionado con interacciones con ciertas versiones de glib2 • http://developer.pidgin.im/ticket/14636 http://developer.pidgin.im/viewmtn/revision/diff/be5e66abad2af29604bc794cc4c6600ab12751f3/with/7eb1f6d56cc58bbb5b56b7df53955d36b9b419b8 http://pidgin.im/news/security/?id=56 http://secunia.com/advisories/46376 http://www.mandriva.com/security/advisories?name=MDVSA-2011:183 http://www.redhat.com/support/errata/RHSA-2011-1371.html https://bugzilla.redhat.com/show_bug.cgi?id=743481 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A18034 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The irc_msg_who function in msgs.c in the IRC protocol plugin in libpurple 2.8.0 through 2.9.0 in Pidgin before 2.10.0 does not properly validate characters in nicknames, which allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted nickname that is not properly handled in a WHO response. La función irc_msg_who en msgs.c en el plugin del protocolo IRC en libpurple v2.8.0 hasta v2.9.0 en Pidgin anterior a v2.10.0 no valida adecuadamente caracteres en nombres de usuario, lo que permite a atacantes remotos asistidos por el usuario provocar una denegación de servicio (desreferenciar un puntero NULL y caída de la aplicación) a través del nombre de usuario que no se maneja adecuadamente en una respuesta WHO. • http://developer.pidgin.im/viewmtn/revision/diff/5749f9193063800d27bef75c2388f6f9cc2f7f37/with/5c2dba4a7e2e76b76e7f472b88953a4316706d43/libpurple/protocols/irc/msgs.c http://developer.pidgin.im/viewmtn/revision/info/5c2dba4a7e2e76b76e7f472b88953a4316706d43 http://pidgin.im/news/security/?id=53 http://secunia.com/advisories/45663 http://secunia.com/advisories/45916 http://securitytracker.com/id?1025961 http://www.openwall.com/lists/oss-security/2011/08/20/2 http://www.openwall.com/lists/oss-security/2011/08/22/2&# •
