Descriptions
idn in libidn before 1.33 might allow remote attackers to obtain sensitive memory information by reading a zero byte as input, which triggers an out-of-bounds read, a different vulnerability than CVE-2015-8948.
idn en libidn en versiones anteriores a 1.33 podría permitir a atacantes remotos obtener información de memoria sensible mediante la lectura de un byte cero como entrada, lo que desencadena una lectura fuera de límites, una vulnerabilidad diferente a CVE-2015-8948.
Thijs Alkemade, Gustavo Grieco, Daniel Stenberg, and Nikos Mavrogiannopoulos discovered that Libidn incorrectly handled invalid UTF-8 characters.

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.
