TITLE:
NetBSD False Intel Hardware RNG Detection Security Issue
SECUNIA ADVISORY ID:
SA19585
VERIFY ADVISORY:
https://secunia.com/advisories/19585/
CRITICAL:
Less critical
IMPACT:
Security Bypass
WHERE:
>From remote
OPERATING SYSTEM:
NetBSD 1.x
https://secunia.com/product/255/
DESCRIPTION:
A security issue has been reported in NetBSD, which can weaken
certain security features.
The problem is that the driver for Intel's RNG (Random Number
Generator) incorrectly detects the device as present on some
hardware. This causes the driver to feed a constant stream of bytes
with value 255 into the entropy pool for the kernel RNG resulting in
poor-quality or highly predictable output.
This may e.g. cause the SSH daemon to use predictable keys on certain
systems.
SOLUTION:
The security issue has been fixed in NetBSD-1-6 branch (February 26,
2006).
PROVIDED AND/OR DISCOVERED BY:
The vendor credits Matthias Scheler.
