Red Hat Software has been notified of a critical security problem (a buffer
overrun) in /usr/bin/sperl*. As no official fix for this problem exists,
we recommend turning off the setuid bit on /usr/bin/sperl*. As far as
we know, this problem affects all platforms and all versions.

As soon as a fix is available we will release a new version of the perl
package and announce it here. If no fix seems forthcoming, we will issue
a new package w/o the setuid bit enabled on /usr/sbin/sperl.

A patch for 5.003_97f has appeared on the Perl5-Porters list.  The entire
codebase is being examined line by line to find any other such conditions.

You can disable the exploits for this bug with the following command:

      chmod u-s /usr/bin/sperl*

Perl 5.003_97g was released tonight.  It should fix that bug.  Any other
overflow problems will be caught and killed before the 5.004 release.
