Package: xsok
Severity: critical
Justification: security hole

This orphaned package still contains the local buffer overflow described
in http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0074 which
leads to privilege escalation (group games).

Seems not to be vulnerable:
djpig@feynman:/usr/src$ xsok -xsokdir `perl -e 'print "X"x3000'`
directory too long

I will close the bug and I will ask Joey to add CAN-2004-0074 to
