The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1755-1 advisory.

  - Yubico libu2f-host 1.1.6 contains unchecked buffers in devs.c, which could enable a malicious token to     exploit a buffer overflow. An attacker could use this to attempt to execute malicious code using a crafted     USB device masquerading as a security token on a computer where the affected library is currently in use.
    It is not possible to perform this attack with a genuine YubiKey. (CVE-2018-20340)

  - In devs.c in Yubico libu2f-host before 1.1.8, the response to init is misparsed, leaking uninitialized     stack memory back to the device. (CVE-2019-9578)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-202004-15 (libu2f-host: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libu2f-host. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to plug-in a malicious USB device,       possibly resulting in execution of arbitrary code with the privileges of       the process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.
