1. Topic:

Updated semi packages that fix vulnerabilities in semi's temporary file
handling are now available for Red Hat Linux 7.1, 7.2, and 7.3.

2. Relevant releases/architectures:

Red Hat Linux 7.1 - noarch
Red Hat Linux 7.1 for iSeries (64 bit) - noarch
Red Hat Linux 7.1 for pSeries (64 bit) - noarch
Red Hat Linux 7.2 - noarch
Red Hat Linux 7.3 - noarch
Red Hat Linux 8.0 - noarch
Red Hat Linux 9 - noarch

3. Problem description:

semi is a MIME library for GNU Emacs and XEmacs used by the wl mail package.

A vulnerability in semi version 1.14.3 and earlier allows an attacker
to overwrite arbitrary files with potentially arbitrary contents using the
privileges of the user running Emacs and semi. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0440
to this issue.

Users of semi are advised to upgrade to these packages, which contain
a backported patch correcting this issue.

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:

up2date

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