31 Aug 2001 — ipfw in FreeBSD does not properly handle the use of "me" in its rules when point to point interfaces are used, which causes ipfw to allow connections from arbitrary remote hosts. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-01:53.ipfw.asc •

23 Aug 2001 — TCP Wrappers (tcp_wrappers) in FreeBSD 4.1.1 through 4.3 with the PARANOID ACL option enabled does not properly check the result of a reverse DNS lookup, which could allow remote attackers to bypass intended access restrictions via DNS spoofing. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-01:56.tcp_wrappers.asc • CWE-863: Incorrect Authorization •

21 Aug 2001 — linprocfs on FreeBSD 4.3 and earlier does not properly restrict access to kernel memory, which allows one process with debugging rights on a privileged process to read restricted memory from that process. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-01:55.procfs.asc •

17 Aug 2001 — fts routines in FreeBSD 4.3 and earlier, NetBSD before 1.5.2, and OpenBSD 2.9 and earlier can be forced to change (chdir) into a different directory than intended when the directory above the current directory is moved, which could cause scripts to perform dangerous actions on the wrong directories. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-01:40.fts.v1.1.asc •

10 Jul 2001 — FreeBSD 4.3 does not properly clear shared signal handlers when executing a process, which allows local users to gain privileges by calling rfork with a shared signal handler, having the child process execute a setuid program, and sending a signal to the child. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-01:42.signal.v1.1.asc •

07 Jul 2001 — Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process. • https://www.exploit-db.com/exploits/20997 •

18 Jun 2001 — Race condition in the UFS and EXT2FS file systems in FreeBSD 4.2 and earlier, and possibly other operating systems, makes deleted data available to user processes before it is zeroed out, which allows a local user to access otherwise restricted information. • http://archives.neohapsis.com/archives/freebsd/2001-03/0403.html •
