CVSS v2.0

2.1

Low

Base vector

AV:L/AC:L/Au:N/C:P/I:N/A:N

Name of the Vulnerable Software and Affected Versions FreeBSD versions 4.x through 4.11 FreeBSD versions 5.x through 5.4

Description The issue is related to the SIOCGIFCONF ioctl, specifically the ifconf function, which does not properly clear a buffer before using it. This allows local users to obtain portions of sensitive kernel memory.

Recommendations For FreeBSD versions 4.x through 4.11, update to a version outside of this range to resolve the issue. For FreeBSD versions 5.x through 5.4, update to a version outside of this range to resolve the issue. As a temporary workaround, consider restricting access to the ifconf function until a patch is available.
