QNX Neutrino RTOS 6.2.0 uses the PATH environment variable to find and execute the cp program while operating at raised privileges, which allows local users to gain privileges by modifying the PATH to point to a malicious cp program.

The timer implementation in QNX RTOS 6.1.0 allows local users to cause a denial of service (hang) and possibly execute arbitrary code by creating multiple timers with a 1-ms tick.

/bin/su in QNX realtime operating system (RTOS) 4.25 and 6.1.0 allows local users to obtain sensitive information from core dump files by sending the SIGSERV (invalid memory reference) signal.

The (1) phrafx and (2) phgrafx-startup programs in QNX realtime operating system (RTOS) 4.25 and 6.1.0 do not properly drop privileges before executing the system command, which allows local users to execute arbitrary commands by modifying the PATH environment variable to reference a malicious crttrap program.

Multiple buffer overflows in realtime operating system (RTOS) 6.1.0 allows local users to execute arbitrary code via (1) a long ABLANG environment variable in phlocale or (2) a long -u option to pkg-installer.

ptrace in the QNX realtime operating system (RTOS) 4.25 and 6.1.0 allows programs to attach to privileged processes, which could allow local users to execute arbitrary code by modifying running processes.

Multiple buffer overflows in QNX RTOS 4.25 may allow attackers to execute arbitrary code via long filename arguments to (1) Watcom or (2) int10.

Certain patches for QNX Neutrino realtime operating system (RTOS) 6.2.0 set insecure permissions for the files (1) /sbin/io-audio by OS Update Patch A, (2) /bin/shutdown, (3) /sbin/fs-pkg, and (4) phshutdown by QNX experimental patches, (5) cpim, (6) vpim, (7) phrelaycfg, and (8) columns, (9) othello, (10) peg, (11) solitaire, and (12) vpoker in the games pack 2.0.3, which allows local users to gain privileges by modifying the files before permissions are changed.

Multiple buffer overflows in the PPPoE daemon (PPPoEd) in QNX RTP 6.1 allow remote attackers to execute arbitrary code via a long argument to the (1) -F, (2) name, (3) en, (4) upscript, (5) downscript, (6) retries, (7) timeout, (8) scriptdetach, (9) noscript, (10) nodetach, (11) remote_mac, or (12) local_mac flags.

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.

A race condition in crrtrap for QNX RTP 6.1 allows local users to gain privileges by modifying the PATH environment variable to reference a malicious io-graphics program before is executed by crrtrap.

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.

QNX Neutrino RTOS 6.3.0 allows local users to cause a denial of service (hang) by supplying a "break *0xb032d59f" command to gdb.

Buffer overflow in phgrafx in QNX 6.2.1 and 6.3.0 allows local users to execute arbitrary code via a long command line argument.

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.

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 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.

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.
