The fix

We hold no Microsoft remediation data for CVE-2000-0703, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

suidperl (aka sperl) does not properly cleanse the escape sequence "~!" before calling /bin/mail to send an error report, which allows local users to gain privileges by setting the "interactive" environmental variable and calling suidperl with a filename that contains the escape sequence.
