EulerOS Virtualization 2.10.0 : util-linux (EulerOS-SA-2022-2041)
medium Nessus Plugin ID 163197
Synopsis
The remote EulerOS Virtualization host is missing multiple security updates.Description
According to the versions of the util-linux package installed, the EulerOS Virtualization 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)
- A logical error was found in util-linux's libmount library in a function that allows unprivileged users to unmount FUSE filesystems. Incorrect uid checking allows unprivileged users to unmount FUSE filesystems with similar uid users, an attacker could exploit this vulnerability to cause a denial of (CVE-2021-3995)
- that allows unprivileged users to unmount FUSE filesystems. Issues related to parsing the /proc/self/mountinfo file allow unprivileged users to unmount other users' filesystems that are themselves world-writable (such as /tmp) or mounted in a world-writable directory. An attacker could exploit this (CVE-2021-3996)
