"An updated ed package that fixes one security issue is now available
for Red Hat Enterprise Linux 2.1, 3, 4 and 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

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."
