CVE-2011-4060

Estado: ModificadaBaja (3.3)—

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.
