CVE-2000-0703
First published: Fri Oct 13 2000(Updated: )
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.
