Name of the Vulnerable Software and Affected Versions
Yubico libu2f-host versions prior to 1.1.8
Description
The issue is caused by a buffer overflow in the devs.c file of the Yubico libu2f-host library, which can lead to a denial of service due to incorrect parsing of the response to the init command. This can potentially allow a remote attacker to exploit the vulnerability.
Recommendations
For versions prior to 1.1.8, update to version 1.1.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the devs.c file or the init command to minimize the risk of exploitation.
Correção
