Multiple stack-based buffer overflows in QNX Neutrino RTOS 6.3.0 allow local users to execute arbitrary code via long (1) ABLPATH or (2) ABLANG environment variables in the libAP library (libAp.so.2) or (3) a long PHOTON_PATH environment variable to the setitem function in the libph library.
Race condition in phfont in QNX Neutrino RTOS 6.2.1 allows local users to execute arbitrary code via unspecified manipulations of the PHFONT and PHOTON2_PATH environment variables.
Multiple buffer overflows in QNX Neutrino RTOS 6.2.0 allow local users to execute arbitrary code via a long first argument to the (1) su or (2) passwd commands.
QNX Neutrino RTOS 6.3.0 ships /etc/rc.d/rc.local with world-writable permissions, which allows local users to modify the file and execute arbitrary code at system startup.
Untrusted search path vulnerability in the crttrap command in QNX Neutrino RTOS 6.2.1 allows local users to load arbitrary libraries via a LD_LIBRARY_PATH environment variable that references a malicious library.
The inputtrap utility in QNX RTOS 6.1.0, 6.3, and possibly earlier versions does not properly check permissions when the -t flag is specified, which allows local users to read arbitrary files.
Untrusted execution path vulnerability in the PPPoE daemon (PPPoEd) in QNX RTP 6.1 allows local users to execute arbitrary programs by modifying the PATH environment variable to point to a malicious mount program.
