Description nobody 2012-10-09 23:50:32 UTC

gcc-config called ldconfig without any path, giving ability for a user to add an ldconfig that root might run when using gcc-config.

grep ldconfig /usr/bin/gcc-config -n
325:			# If we previously had stuff in /, make sure ldconfig gets re-run.
481:			ldconfig

It should called /sbin/ldconfig


Reproducible: Always

no explanation as to how this could possibly be a problem.  you could make the same argument for cp, mv, touch, sed, env-update, or any other program.

i assume if you make an ldconfig in a directory with +x the call for ldconfig might run that version instead of /sbin one.
i was wrong, something i should have try before.
sorry for the noise.
