Red Hat: 'sgml-tools' vulnerability
Posted by LinuxSecurity.com Team   
RedHat Linux Temporary files (in the sgml-tools package) were created without any special permissions, and so in most cases would be world-readable.

Synopsis:          Updated sgml-tools packages fix insecure temporary file handling
Advisory ID:       RHSA-2001:027-02

1. Topic:

Insecure handling of temporary file permissions could lead to other users
on a multi-user system being able to read the documents being converted.

2. Relevant releases/architectures:

Red Hat Linux 5.2 - alpha, i386, sparc

Red Hat Linux 6.2 - alpha, i386, sparc

Red Hat Linux 7.0 - alpha, i386

3. Problem description:

Temporary files were created without any special permissions, and so in
most cases would be world-readable.  The fixed packages create a secure
temporary directory first (readable only by the owner), and then create
temporary files inside that.

4. Solution:

To update all RPMs for your particular architecture, run:

rpm -Fvh 

where  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 directly *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:

up2date

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