Descriptions

A vulnerability was found in pkcs15-init in OpenSC. An attacker could use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly accessed.

A vulnerability was found in pkcs15-init in OpenSC. An attacker could use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. Insufficient or missing checking of return values of functions leads to unexpected work with variables that have not been initialized.

USN-7346-1 fixed vulnerabilities in OpenSC. The update introduced a regression which broke smartcard based authentication. This update fixes the problem. 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.
