Descriptions

The stringprep_utf8_to_ucs4 function in libin before 1.31, as used in jabberd2, allows context-dependent attackers to read system memory and possibly have other unspecified impact via invalid UTF-8 characters in a string, which triggers an out-of-bounds read.

Vulnerabilidad en la función stringprep_utf8_to_ucs4 en libin en versiones anteriores a 1.31, tal como se utiliza en jabberd2, permite a atacantes dependientes del contexto leer la memoria del sistema y posiblemente tener otro impacto no especificado a través de caracteres UTF-8 no válidos en una cadena, lo que desencadena una lectura fuera de rango.

Thijs Alkemade, Gustavo Grieco, Daniel Stenberg, and Nikos Mavrogiannopoulos discovered that Libidn incorrectly handled invalid UTF-8 characters. A remote attacker could use this issue to cause Libidn to crash, resulting in a denial of service, or possibly disclose sensitive memory. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Hanno Boeck discovered that Libidn incorrectly handled certain input. A remote attacker could possibly use this issue to cause Libidn to crash, resulting in a denial of service. Various other issues were also addressed.
