ipfw in FreeBSD 5.4, when running on Symmetric Multi-Processor (SMP) or Uni Processor (UP) systems with the PREEMPTION kernel option enabled, does not sufficiently lock certain resources while performing table lookups, which can cause the cache results to be corrupted during multiple concurrent lookups, allowing remote attackers to bypass intended access restrictions. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:13.ipfw.asc •

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. • https://www.exploit-db.com/exploits/1008 ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:15.tcp.asc ftp://ftp.sco.com/pub/updates/UnixWare/SCOSA-2005.64/SCOSA-2005.64.txt http://secunia.com/advisories/15393 http://secunia.com/advisories/15417 http://secunia.com/advisories/18222 http://secunia.com/advisories/18662 http://support.avaya.com/elmodocs2/security/ASA-2006-032.htm http://www.cisco.com/warp/public/707/cisco-sn-20050518-tcpts.shtml http:/& •

The kernel in FreeBSD 4.x to 4.11 and 5.x to 5.4 does not properly clear certain fixed-length buffers when copying variable-length data for use by applications, which could allow those applications to read previously used sensitive memory. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:08.kmem.asc http://lists.apple.com/archives/security-announce/2005/Oct/msg00000.html http://secunia.com/advisories/17368 http://www.securityfocus.com/bid/13526 http://www.securityfocus.com/bid/15252 http://www.vupen.com/english/advisories/2005/2256 •
