Sorry, ik zie de relatie even niet tussen ptrace en Nvidia...
Description:
A vulnerability has been reported in FreeBSD, which can be
exploited by malicious, local users to cause a DoS (Denial
of Service).
The vulnerability is caused due to a signedness error in the
"PT_LWPINFO" ptrace command and can be exploited to trigger
a kernel panic or potentially corrupt user-space memory.
The vulnerability is reported in version 6.0-RELEASE and
does reportedly not affect 6.1-RELEASE. Other versions may
also be affected.
Solution:
Grant only trusted users access to affected systems.
NB. Ptrace en alle andere debug zaken staan bij mij uit (wat je ook moet doen op productie systemen).. En ik draai RELENG_6 (6.2-PRERELEASE op dit moment)..
