This affects all recent Perl versions, including all 5.8 version.
Here is some more information:

The fix in the advisory is not really correct; better fixes have
been applied to both the 5.8 and 5.9 tracks in the Perl repository.

It affects all platforms, but the only known exploit is for Webmin, a
Unix web administration tool. This bug can only be exploited if an
attacker can specify the *format* string passed to printf() or
sprintf().

This bug and related issues are fixed in Perl 5.8.8 which will be
released in a couple of weeks.
