QNX : Security Vulnerabilities, CVEs, CVSS score >= 1

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.

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.

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

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.

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 dhcp.client program for QNX 4.25 vmware is setuid, possibly by default, which allows local users to modify the NIC configuration and conduct other attacks.

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.

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 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.

Format string vulnerability in QNX 6.1 FTP client allows remote authenticated users to gain group bin privileges via format string specifiers in the QUOTE command.

Multiple buffer overflows in (1) phrelay-cfg, (2) phlocale, (3) pkg-installer, or (4) input-cfg in QNX Photon microGUI for QNX RTP 6.1 allow local users to gain privileges via a long -s (server) command line parameter.

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.

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.

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.

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

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 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.

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.

/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 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.

Multiple buffer overflows in QNX 4.25 may allow local users to execute arbitrary code via long command line arguments to (1) sample, (2) ex, (3) du, (4) find, (5) lex, (6) mkdir, (7) rm, (8) serserv, (9) tcpserv, (10) termdef, (11) time, (12) unzip, (13) use, (14) wcc, (15) wcc386, (16) wd, (17) wdisasm, (18) which, (19) wlib, (20) wlink, (21) wpp, (22) wpp386, (23) wprof, (24) write, or (25) wstrip.

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.
