3.3
CVSS v3.1
Official Description
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.
Technical Analysis
CVE-2011-4060 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
