CVE-2017-16997

Priority
Description
elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26
mishandles RPATH and RUNPATH containing $ORIGIN for a privileged (setuid or
AT_SECURE) program, which allows local users to gain privileges via a
Trojan horse library in the current working directory, related to the
fillin_rpath and decompose_rpath functions. This is associated with
misinterpretion of an empty RPATH/RUNPATH token as the "./" directory.
NOTE: this configuration of RPATH/RUNPATH for a privileged program is
apparently very uncommon; most likely, no such program is shipped with any
common Linux distribution.
