According to the versions of the util-linux packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU (Time-of-Check-     Time-of-Use) vulnerability has been identified in the SUID binary /usr/bin/mount from util-linux. The     mount binary, when setting up loop devices, validates the source file path with user privileges via fork()     + setuid() + realpath(), but subsequently re-canonicalizes and opens it with root privileges (euid=0)     without verifying that the path has not been replaced between both operations. Neither O_NOFOLLOW, nor     inode comparison, nor post-open fstat() are employed. This allows a local unprivileged user to replace the     source file with a symlink pointing to any root-owned file or device during the race window, causing the     SUID binary to open and mount it as root. Exploitation requires an /etc/fstab entry with user,loop options     whose path points to a directory where the attacker has write permission, and that /usr/bin/mount has the     SUID bit set (the default configuration on virtually all Linux distributions). The impact is unauthorized     read access to root-protected files and block devices, including backup images, disk volumes, and any file     containing a valid filesystem. This issue has been patched in version 2.41.4.(CVE-2026-27456)

    Several vulnerabilities were discovered in util-linux which could result     in privilege escalation.

    For the stable distribution (trixie), these problems have been fixed in     version 2.41.5-0+deb13u1.

    We recommend that you upgrade your util-linux packages.

According to the versions of the util-linux packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    A flaw was found in util-linux. This vulnerability allows a heap buffer overread when processing 256-byte     usernames, specifically within the `setpwnam()` function, affecting SUID (Set User ID) login-utils     utilities writing to the password database.(CVE-2025-14104)

    A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked     with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote     attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based     Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names.
    This could lead to unauthorized access.(CVE-2026-3184)
