According to the versions of the jose packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
latchset jose through version 11 allows attackers to cause a denial of service (CPU consumption) via a large p2c (aka PBES2 Count) value.(CVE-2023-50967)
Tenable has extracted the preceding description block directly from the EulerOS jose security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
