Descriptions

elf/dl-load.c in ld.so in the GNU C Library (aka glibc or libc6) through 2.11.2, and 2.12.x through 2.12.1, does not properly handle a value of $ORIGIN for the LD_AUDIT environment variable, which allows local users to gain privileges via a crafted dynamic shared object (DSO) located in an arbitrary directory.

elf/dl-load.c de ld.so en la Biblioteca GNU C (también conocida como glibc o libc6) hasta v2.11.2, y v2.12.x hasta v2.12.1 no maneja adecuadamente un valor de $ORIGIN de la variable de entorno LD_AUDIT, esto permite a usuarios locales aumentar sus privilegios mediante un objeto dinámico compartido (DSO) ubicado en un directorio aleatorio.

The GNU C library dynamic linker suffers from an $ORIGIN expansion vulnerability.
