In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain file with a symlink during use of the POSIX "-R -L" options, which allows local users to modify the ownership of arbitrary files by leveraging a race condition.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - coreutils: memory corruption flaw in parse_datetime() (CVE-2014-9471)

  - coreutils: Non-privileged session can escape to the parent session in chroot (CVE-2016-2781)

  - coreutils: race condition vulnerability in chown and chgrp (CVE-2017-18018)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - coreutils: memory corruption flaw in parse_datetime() (CVE-2014-9471)

  - coreutils: race condition vulnerability in chown and chgrp (CVE-2017-18018)

  - The SUSE coreutils-i18n.patch for GNU coreutils allows context-dependent attackers to cause a denial of     service (segmentation fault and crash) via a long string to the sort command, when using the (1) -d or (2)
    -M switch, which triggers a stack-based buffer overflow in the alloca function. (CVE-2013-0221)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 4 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - coreutils: tty hijacking possible in su via TIOCSTI ioctl (CVE-2005-4890)

  - coreutils: race condition vulnerability in chown and chgrp (CVE-2017-18018)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - coreutils: memory corruption flaw in parse_datetime() (CVE-2014-9471)

  - coreutils: Non-privileged session can escape to the parent session in chroot (CVE-2016-2781)

  - coreutils: race condition vulnerability in chown and chgrp (CVE-2017-18018)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to the version of the coreutils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - In GNU Coreutils through 8.29, chown-core.c in chown     and chgrp does not prevent replacement of a plain file     with a symlink during use of the POSIX '-R -L' options,     which allows local users to modify the ownership of     arbitrary files by leveraging a race     condition.(CVE-2017-18018)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the version of the coreutils package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :
