CVE-2000-0703: Larry Wall Perl

High severity, CVSS 7.2. EPSS: 1.1% chance of exploitation in the next 30 days.

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.

Affected products
