-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I misread a '1' for an 'l' on the exploit. X blows up quite handily now. John - -----Original Message----- From: owner-freebsd-security@freebsd.org [mailto:owner-freebsd-security@freebsd.org]On Behalf Of Barnes, John Sent: Friday, February 13, 2004 9:25 AM To: 'freebsd-security@freebsd.org' Subject: XFree86 Font Information File Buffer Overflow Has anyone see this alert? http://www.securityfocus.com/archive/1/353352 It seems to work on Linux, but when I tried the proof of concept on 4.3.0,1 running 5.2 RELEASE, I couldn't get the X server to core dump or segmentation fault. So, it seems likely to me that FreeBSD is not vulnerable to this. Any other thoughts on this matter?
