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.

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 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.

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.

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.
