|

| 7 | This document describes differences between the 5.7.1 release and the
|
|---|
| 8 | 5.7.2 release.

|
|---|
| 11 | release, see L<perl570delta>. To view the differences between the
|

| 14 | =head1 Security Vulnerability Closed
|
|---|
| 15 |
|
|---|
| 16 | (This change was already made in 5.7.0 but bears repeating here.)
|
|---|
| 17 |
|
|---|
| 18 | A security vulnerability affecting all Perl versions prior to 5.6.1
|
|---|
| 19 | was found in August 2000. The vulnerability does not affect default
|
|---|
| 20 | installations and as far as is known affects only the Linux platform.
|
|---|
| 21 |
|
|---|
| 22 | You should upgrade your Perl to 5.6.1 as soon as possible. Patches
|
|---|
| 23 | for earlier releases exist but using the patches require full
|
|---|
| 24 | recompilation from the source code anyway, so 5.6.1 is your best
|
|---|
| 25 | choice.

| 30 | =head1 Incompatible Changes
|
|---|
| 31 |
|
|---|
| 32 | =head2 64-bit platforms and malloc
|
|---|
| 33 |
|
|---|
| 34 | If your pointers are 64 bits wide, the Perl malloc is no more being
|
|---|
| 35 | used because it simply does not work with 8-byte pointers. Also,
|
|---|
| 36 | usually the system malloc on such platforms are much better optimized
|
|---|
| 37 | for such large memory models than the Perl malloc.
