ed security update

CentOS Errata and Security Advisory CESA-2008:0946-01

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.
