The UW imap package contained various buffer overflow vulnerabilities
which can lead to breach of security on a host running the imap and pop
services from this package.

Several buffer overflow vulnerabilities have been found by both the
authors of UW imap and others. The vulnerabilities are only
exploitable after a user has authenticated with the server, giving
a remote shell restricted to the permissions of the authenticated

Impact: Systems that already allow users remote shell access are
not affected by the buffer overflow vulnerabilities; however, it is
highly recommended that all systems be upgraded to this release,
as it fixes other server crabugs as well.

In addition, imap server crashing problems related to messages
containing null characters in the message body have been fixed in
this release.


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]

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.

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.
