I.e., if you can pass BASH_FUNC_name%% then it will still crash/execute code. Chet is working on patches for them, http://www.openwall.com/lists/oss-security/2014/10/01/25. Our bash is immune to this due to disabling function imports. The bashcheck script is wrong currently though and I've submitted a pull request to fix it here: https://github.com/hannob/bashcheck/pull/23 I've just committed 4.3.28 as well. --=20 Regards, Bryan Drewery --eWqXEcGApowBsDQAqUL4bmCctXOP8nPxf Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) iQEcBAEBAgAGBQJULJtwAAoJEDXXcbtuRpfP8wIH/08Kromlma77SVQYUnAyPjHI qWSzOytkZ+jLRHcMETrvhByVmSnZF111lw2y/G1IcLtVJ142llwHAuVW8vjojUk6 x1/eHhicCPKM04KS1r3ZP4XP97FoyQ21qI2j7Bz3QbaoaKkfmRfk9hXU92owkuoO JLgV5mQJeADyUwg5Jb5UscPhEaJ1D52Brs0cCqjP206nQ30k22KJb1XYFEPXFDkp 0GHVkF8lMiryflacSPeE1va0yCT2Fl1axJGrpxsvrw/f62pCZQGQknfuHU3TL7xN 2UM1wkzgsO99njVJRKYfimyAmlktT99FlOau0p7P95vpigpDCDDUnJERnqeZdbY= =vw79 -----END PGP SIGNATURE----- --eWqXEcGApowBsDQAqUL4bmCctXOP8nPxf--
