An integer overflow vulnerability in the calloc() function of the C runtime library of affected versions of BlackBerry® QNX Software Development Platform (SDP) version(s) 6.5.0SP1 and earlier, QNX OS for Medical 1.1 and earlier, and QNX OS for Safety 1.0.1 and earlier that could allow an attacker to potentially perform a denial of service or execute arbitrary code.

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.

In BlackBerry QNX Software Development Platform (SDP) 6.6.0 and 6.5.0 SP1 and earlier, an information disclosure vulnerability in the default configuration of the QNX SDP could allow an attacker to gain information relating to memory layout of higher privileged processes by manipulating environment variables that influence the loader.
