Description

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 LD_AUDIT 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 trusted library directory, as demonstrated by libpcprofile.so.

Affected products

• GNU C Library (glibc): through 2.11.2; 1.00, 1.01, 1.02, 1.03, 1.04, 1.05 (+48)
