|Summary:||The remote host is missing an update for the 'sudo'; package(s) announced via the referenced advisory.|
The remote host is missing an update for the 'sudo'
package(s) announced via the referenced advisory.
The sudo (superuser do) utility allows system administrators to give
certain users the ability to run commands as root.
An insecure temporary file use flaw was found in the sudo package's
post-uninstall script. A local attacker could possibly use this flaw to
overwrite an arbitrary file via a symbolic link attack, or modify the
contents of the '/etc/nsswitch.conf' file during the upgrade or removal of
the sudo package. (CVE-2012-3440)
This update also fixes the following bugs:
* Previously, sudo escaped non-alphanumeric characters in commands using
'sudo -s' or 'sudo -' at the wrong place and interfered with the
authorization process. Some valid commands were not permitted. Now,
non-alphanumeric characters escape immediately before the command is
executed and no longer interfere with the authorization process.
All users of sudo are advised to upgrade to this updated package, which
contains backported patches to correct these issues.
sudo on Red Hat Enterprise Linux (v. 5 server)
