Normally it is the policy of the FreeBSD Security Team to not publicly discuss security issues until an advisory is ready, but in this case since exploit code is already widely available I want to make a patch available ASAP. Due to the short timeline, it is possible that this patch will not be the final version which is provided when an advisory is sent out; it is even possible (although highly doubtful) that this patch does not fully fix the issue or introduces new issues -- in short, use at your own risk (even more than usual). The patch is at http://people.freebsd.org/~cperciva/rtld.patch and has SHA256 hash ffcba0c20335dd83e9ac0d0e920faf5b4aedf366ee5a41f548b95027e3b770c1 I expect a full security advisory concerning this issue will go out on Wednesday December 2nd. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (FreeBSD) iEYEARECAAYFAksUbjcACgkQFdaIBMps37LP9ACgljaYCfgVuhD2gd9Natpq4H/9 i48An1mgl+Mih+AWN7J9KZ1rsiEU31IZ =MPXj -----END PGP SIGNATURE----- -- Colin Percival Security Officer, FreeBSD | freebsd.org | The power to serve Founder / author, Tarsnap | tarsnap.com | Online backups for the truly paranoid
