[原文]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.


[CNNVD]QNX Neutrino本地权限提升漏洞(CNNVD-200602-111)

        QNX Neutrino是嵌入式设备的微内核实时操作系统。
        QNX Neutrino的"phgrafx"工具中存在缓冲区溢出漏洞,恶意用户可以利用这个漏洞在本地获得权限提升。
        例如:
        qnx$ uname -a; id
        QNX qnx 6.3.0 2004/04/29-21:23:19UTC x86pc x86
        uid=6(deadbeef) gid=1(bin) groups=0(root),3(sys),4(adm),5(tty)
        qnx$ gcc phex.c -o phex -W
        qnx$ ./phex
        shellcode length: 21
        address: 0x8047a2c
        Warning: can not find palette under '55

22964
QNX Neutrino RTOS libph Library PHOTON_PATH Environment Variable Local Overflow
Local Access Required Input Manipulation
Loss of Integrity

- 漏洞描述

QNX Neutrino RTOS contains a flaw that may allow a local attacker to elevate their privileges. The issue is due to the improper handling of environment variables in the libph library (used by many applications in the Photon API package). The libph system library (libph.so.3) does not check the bounds on user-supplied input to the PHOTON_PATH variable allowing a user to overflow the setitem() function, which will execute arbitrary code under the privilege of the utility calling the library. Since many of the applications linked against libph.so.3 are SUID, there are many vectors for using this to leverage privileged access.

- 解决方案

Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: remove the setuid bit from any programs linked to libph.so.3
