QNX Neutrino RTOS libAP ApFindTranslationFile() buffer overflow
| qnx-libap-bo (24558) |  High Risk |
Description:
QNX Neutrino RTOS is vulnerable to a stack-based buffer overflow in the libAP library, caused by improper bounds checking by the ApFindTranslationFile() function. By supplying an overly long ABLPATH environment variable, a local attacker could overflow and execute arbitrary code on the system with root privileges.
Note: An attacker could also exploit this vulnerability using the ABLANG environment variable.
