Categoría:FreeBSD Local Security Checks
Título:FreeBSD Security Advisory (FreeBSD-SA-04:15.syscons.asc)
Resumen:The remote host is missing an update to the system; as announced in the referenced advisory FreeBSD-SA-04:15.syscons.asc
Descripción:Summary:
The remote host is missing an update to the system
as announced in the referenced advisory FreeBSD-SA-04:15.syscons.asc

Vulnerability Insight:
syscons(4) is the default console driver for FreeBSD. Using the
physical keyboard and screen, it provides multiple virtual terminals
which appear as if they were separate terminals. One virtual terminal
is considered current and exclusively occupies the screen and the
keyboard. The other virtual terminals are placed in the background.

The syscons CONS_SCRSHOT ioctl(2) does insufficient validation of
its input arguments. In particular, negative coordinates or large
coordinates may cause unexpected behavior.

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

CVSS Score:
