Descriptions
The _dl_unsetenv function in loader.c in the ELF ld.so in OpenBSD 3.9 and 4.0 does not properly remove duplicate environment variables, which allows local users to pass dangerous variables such as LD_PRELOAD to loading processes, which might be leveraged to gain privileges.
La función _dl_unsetenv en loader.c en el ELF ld.so en OpenBSD 3.9 y 4.0 no borra adecuadamente variables de entorno duplicadas, lo cual permite a usuarios locales pasar variables peligrosas como LD_PRELOAD a procesos de carga, lo cual puede ser utilizado para obtener privilegios.
