Descriptions

A heap-based buffer overflow vulnerability was found in the libopensc OpenPGP driver. A crafted USB device or smart card with malicious responses to the APDUs during the card enrollment process using the `pkcs15-init` tool may lead to out-of-bound rights, possibly resulting in arbitrary code execution.

Se encontró una vulnerabilidad de desbordamiento de búfer en el montón en el controlador OpenPGP de libopensc. Un dispositivo USB o una tarjeta inteligente creados con respuestas maliciosas a las APDU durante el proceso de inscripción de la tarjeta mediante la herramienta `pkcs15-init` pueden generar derechos fuera de los límites, lo que posiblemente dé como resultado la ejecución de código arbitrario.

It was discovered that OpenSC did not correctly handle certain memory operations, which could lead to a use-after-free vulnerability. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.
