In BlackBerry QNX Software Development Platform (SDP) 6.6.0 and 6.5.0 SP1 and earlier, a loss of integrity vulnerability in the default configuration of the QNX SDP could allow an attacker being able to reduce the entropy of the PRNG, making other blended attacks more practical by gaining control over environmental factors that influence seed generation.

Weakness

The lack of entropy available for, or used by, a Pseudo-Random Number Generator (PRNG) can be a stability and security threat.
