| 16 | <note><para>Ed isn't something which many people use. It's installed here
|
|---|
| 17 | because it can be used by the patch program if you encounter an ed-based patch
|
|---|
| 18 | file. This happens rarely because diff-based patches are preferred these
|

| 19 | days.</para></note>

| 21 | <para>Ed normally uses the mktemp function to create temporary files in
|
|---|
| 22 | <filename class="directory">/tmp</filename>, but this function contains a
|
|---|
| 23 | vulnerability (see the section on Temporary Files in <ulink
|
|---|
| 24 | url="http://en.tldp.org/HOWTO/Secure-Programs-HOWTO/avoid-race.html"/>). The
|
|---|
| 25 | following patch makes Ed use mkstemp instead, which is the recommended way to
|
|---|
| 26 | create temporary files.</para>

| 40 | <para>This package has a test suite available which can perform a number of
