Posted by Team   
RedHat Linux The version of mktemp shipped with Red Hat Linux prior to version 7 does not support creating temporary directories.

                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated mktemp packages available
Advisory ID:       RHSA-2001:070-02
Issue date:        2001-05-15
Updated on:        2001-05-21
Product:           Red Hat Linux
Keywords:          mktemp directory creation -d
Cross references:  

1. Topic:

The version of mktemp shipped with Red Hat Linux prior to version 7 does 
not support creating temporary directories.

2. Relevant releases/architectures:

Red Hat Linux 5.2 - alpha, i386, sparc

Red Hat Linux 6.2 - alpha, i386, sparc

3. Problem description:

Older versions of mktemp don't support the "-d" parameter to create 
temporary directories safely.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed  (http://bugzilla.Red for more info):

6. RPMs required:

Red Hat Linux 6.2:
