glibc: ld.so arbitrary DSO loading via LD_AUDIT in setuid/setgid programs

ld.so in the GNU C Library aka glibc or libc6 before 2.11.3, and 2.12.x before 2.12.2, does not properly restrict use of the LDAUDIT environment variable to reference dynamic shared objects DSOs as audit objects, which allows local users to gain privileges by leveraging an unsafe DSO located in a...
