Photon microGUI in QNX Neutrino realtime operating system (RTOS) 6.1.0 and 6.2.0 allows attackers to read user clipboard information via a direct request to the 1.TEXT file in a directory whose name is a hex-encoded user ID.

Format string vulnerability in fontsleuth in QNX Neutrino RTOS 6.3.0 allows local users to execute arbitrary code via format string specifiers in the zeroth argument (program name).

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