Descriptions

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
