* Add a testcase for copy reloc against protected dataH.J. Lu2015-03-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linkers in some versions of binutils 2.25 and 2.26 don't support protected data symbol with error messsage like: /usr/bin/ld: copy reloc against protected `bar' is invalid /usr/bin/ld: failed to set dynamic section sizes: Bad value We check if linker supports copy reloc against protected data symbol to avoid running the test if linker is broken. Cherry-pick from master: 83569fb894050db7430047da2219ca50c68f882a [BZ #17711] * config.make.in (have-protected-data): New. * configure.ac: Check linker support for protected data symbol. * configure: Regenerated. * elf/Makefile (modules-names): Add tst-protected1moda and tst-protected1modb if $(have-protected-data) is yes. (tests): Add tst-protected1a and tst-protected1b if $(have-protected-data) is yes. ($(objpfx)tst-protected1a): New. ($(objpfx)tst-protected1b): Likewise. (tst-protected1modb.so-no-z-defs): Likewise. * elf/tst-protected1a.c: New file. * elf/tst-protected1b.c: Likewise. * elf/tst-protected1mod.h: Likewise. * elf/tst-protected1moda.c: Likewise. * elf/tst-protected1modb.c: Likewise.

* CVE-2013-2207, BZ #15755: Disable pt_chown.Carlos O'Donell2013-07-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | The helper binary pt_chown tricked into granting access to another user's pseudo-terminal. Pre-conditions for the attack: * Attacker with local user account * Kernel with FUSE support * "user_allow_other" in /etc/fuse.conf * Victim with allocated slave in /dev/pts Using the setuid installed pt_chown and a weak check on whether a file descriptor is a tty, an attacker could fake a pty check using FUSE and trick pt_chown to grant ownership of a pty descriptor that the current user does not own. It cannot access /dev/pts/ptmx however. In most modern distributions pt_chown is not needed because devpts is enabled by default. The fix for this CVE is to disable building and using pt_chown by default. We still provide a configure option to enable hte use of pt_chown but distributions do so at their own risk.

* Make sunrpc code usable againAndreas Jaeger2012-05-101-0/+1
| | | | | | | | New configure option --enable-obsolete-rpc makes the deprecated RPC headers and functions available at compile time as they were before version 2.14. This option will be removed at some time in the future after the TI-RPC library becomes fully sufficient for the needs of existing applications.
