Description Sean McGovern 2012-12-31 20:27:27 MST

Adding -fstack-protector to the command generated by libtool allows this and other binaries to build successfully.

Comment 1 Sean McGovern 2012-12-31 20:27:52 MST

Oops, wrong version -- this is from 1.8.6_p3.

Comment 2 Todd C. Miller 2013-01-01 07:51:01 MST

Currently, -fstack-protector is part of LT_LDFLAGS which is only used when building shared objects.  It should probably be split out into its own setting as was done for the PIE flags.

Comment 3 Todd C. Miller 2013-01-16 11:51:55 MST

Fixed in sudo 1.8.6p4.
