RedHat Linux Procmail, an autonomous mail processor, as shipped in Red Hat Linux 5.2,6.2, 7, and 7.1, handles signals unsafely.

                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated procmail packages available for Red Hat Linux 5.2, 6.2, 7 and 7.1
Advisory ID:       RHSA-2001:093-03

1. Topic:

Procmail, an autonomous mail processor, as shipped in Red Hat Linux 5.2,
6.2, 7, and 7.1, handles signals unsafely.

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

Red Hat Linux 7.1 - alpha, i386, ia64

3. Problem description:

Procmail was not handling signals properly. This has been fixed in procmail
3.21.

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.
