Thanks in advance for your consideration. This doesn't look like a globbing attempt, but other services certainly could be vulnerable to the buffer overflow, since glob() is in libc (this was noted in the advisory, I believe). Recompile libc and any statically-linked servers, etc. Kris --jKBxcB1XkHIR0Eqt Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.4 (FreeBSD) Comment: For info see http://www.gnupg.org iD8DBQE65crBWry0BWjoQKURAt1UAJ9ylrLqEFOY+q948MCL0r64cdZRaACfVXYp 4jW4a5IFtC+ESuatLLLu4pw= =ft5R -----END PGP SIGNATURE----- --jKBxcB1XkHIR0Eqt-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
