3. Description:

ed is a line-oriented text editor, used to create, display, and modify
text files (both interactively and via shell scripts).

A heap-based buffer overflow was discovered in the way ed, the GNU line
editor, processed long file names. An attacker could create a file with a
specially-crafted name that could possibly execute an arbitrary code when
opened in the ed editor. (CVE-2008-3916)

Users of ed should upgrade to this updated package, which contains
a backported patch to resolve this issue.

4. Solution:

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

This update is available via Red Hat Network.  Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bugs fixed (http://bugzilla.redhat.com/):

462584 - CVE-2008-3916 ed: Heap-based buffer overflow (arb. code execution)
