DESCRIPTION:
A security issue has been reported in VxWorks, which can be exploited
by malicious people to conduct brute force attacks.

The problem is that the loginLib's standard authentication API
("loginDefaultEncrypt()" function) uses an insecure hash algorithm,
which is vulnerable to e.g. collision attacks. This can be exploited
to brute force a character combination producing the target hash.

Successful exploitation requires that a valid login name is known.

SOLUTION:
The vendor has issued patches removing the 80 characters limitation
for encrypted password string length limitation for VxWorks versions
5.5.1 through 6.4. Reportedly, VxWorks 6.9 will include a more secure
default hash algorithm.
