Memory leak in FreeBSD 4.5 and earlier allows remote attackers to cause a denial of service (memory exhaustion) via ICMP echo packets that trigger a bug in ip_output() in which the reference count for a routing table entry is not decremented, which prevents the entry from being removed. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-02:21.tcpip.asc http://www.iss.net/security_center/static/8893.php http://www.osvdb.org/5232 http://www.securityfocus.com/bid/4539 • CWE-401: Missing Release of Memory after Effective Lifetime •

The TCP implementation in various BSD operating systems (tcp_input.c) does not properly block connections to broadcast addresses, which could allow remote attackers to bypass intended filters via packets with a unicast link layer address and an IP broadcast address. • ftp://patches.sgi.com/support/free/security/advisories/20030604-01-I http://cvsweb.netbsd.org/bsdweb.cgi/syssrc/sys/netinet/tcp_input.c.diff?r1=1.136&r2=1.137 http://online.securityfocus.com/archive/1/262733 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=35022 http://www.iss.net/security_center/static/8485.php http://www.openbsd.org/cgi-bin/cvsweb/src/sys/netinet/tcp_input.c.diff?r1=1.109&r2=1.110 http://www.osvdb.org/5308 http://www.securityfocus.com/bi •

FreeBSD 4.5 and earlier, and possibly other BSD-based operating systems, allows local users to write to or read from restricted files by closing the file descriptors 0 (standard input), 1 (standard output), or 2 (standard error), which may then be reused by a called setuid process that intended to perform I/O on normal files. • https://www.exploit-db.com/exploits/21407 ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-02:23.stdio.asc http://archives.neohapsis.com/archives/vulnwatch/2002-q2/0033.html http://online.securityfocus.com/archive/1/268970 http://online.securityfocus.com/archive/1/269102 http://www.ciac.org/ciac/bulletins/m-072.shtml http://www.iss.net/security_center/static/8920.php http://www.kb.cert.org/vuls/id/809347 http://www.osvdb.org/6095 http://www.secu •
