Kategorie:FreeBSD Local Security Checks
Titel:FreeBSD Security Advisory (FreeBSD-SA-09:06.ktimer.asc)
Zusammenfassung:The remote host is missing an update to the system; as announced in the referenced advisory FreeBSD-SA-09:06.ktimer.asc
Beschreibung:Summary:
The remote host is missing an update to the system
as announced in the referenced advisory FreeBSD-SA-09:06.ktimer.asc

Vulnerability Insight:
In FreeBSD 7.0, support was introduced for per-process timers as defined
in the POSIX realtime extensions. This allows a process to have a limited
number of timers running at once, with various actions taken when each
timer reaches zero.

An integer which specifies which timer a process wishes to operate upon is
not properly bounds-checked.

Solution:
Upgrade your system to the appropriate stable release
or security branch dated after the correction date.

CVSS Score:
7.2
