According to the versions of the util-linux packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an 'INPUTRC' environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation.
This flaw affects util-linux versions prior to 2.37.4.(CVE-2022-0563)
Tenable has extracted the preceding description block directly from the EulerOS util-linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
