Description
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.
Public exploit
An exploit or proof of concept is public: anyone can try it against an unpatched system. The public collections list 2 Metasploit modules and 4 Exploit-DB entries for it. 2 references of the record are tagged as an exploit.
