/sbin/pppoectl in BlackBerry QNX Neutrino RTOS 6.4.x and 6.5.x allows local users to obtain sensitive information by reading "bad parameter" lines in error messages, as demonstrated by reading the root password hash in /etc/shadow.

/sbin/ifwatchd in BlackBerry QNX Neutrino RTOS 6.4.x and 6.5.x allows local users to gain privileges by providing an arbitrary program name as a command-line argument.

Stack-based buffer overflow in the bpedecompress function in (1) BlackBerry QNX Neutrino RTOS through 6.5.0 SP1 and (2) QNX Momentics Tool Suite through 6.5.0 SP1 in the QNX Software Development Platform allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted packets to TCP port 4868.

The runtime linker in QNX Neutrino RTOS 6.5.0 before Service Pack 1 does not properly clear the LDDEBUGOUTPUT and LDDEBUG environment variables when a program is spawned from a setuid program, which allows local users to overwrite files via a symlink attack.
