QNX Neutrino RTOS libph setitem() buffer overflow
| qnx-libph-bo (24557) |  High Risk |
Description:
QNX Neutrino RTOS is vulnerable to a stack-based buffer overflow in the libph library, caused by improper bounds checking by the setitem() function. By supplying an overly long PHOTON_PATH environment variable, a local attacker could overflow and execute arbitrary code on the system with root privileges.
Platforms Affected:
- QNX, QNX Neutrino RTOS 6.3.0
Remedy:
No remedy available as of July 4, 2009.
Consequences:
Gain Privileges
