2009-12-31 CVE-2009-4502 Permissions, Privileges, and Access Controls vulnerability in Zabbix
The NET_TCP_LISTEN function in net.c in Zabbix Agent before 1.6.7, when running on FreeBSD or Solaris, allows remote attackers to bypass the EnableRemoteCommands setting and execute arbitrary commands via shell metacharacters in the argument to net.tcp.listen.

2009-02-20 CVE-2009-0641 Permissions, Privileges, and Access Controls vulnerability in Freebsd
sys_term.c in telnetd in FreeBSD 7.0-RELEASE and other 7.x versions deletes dangerous environment variables with a method that was valid only in older FreeBSD distributions, which might allow remote attackers to execute arbitrary code by passing a crafted environment variable from a telnet client, as demonstrated by an LD_PRELOAD value that references a malicious library.

2008-10-03 CVE-2008-2476 Improper Input Validation vulnerability in multiple products
The IPv6 Neighbor Discovery Protocol (NDP) implementation in (1) FreeBSD 6.3 through 7.1, (2) OpenBSD 4.2 and 4.3, (3) NetBSD, (4) Force10 FTOS before E7.7.1.1, (5) Juniper JUNOS, and (6) Wind River VxWorks 5.x through 6.4 does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity) or read private network traffic via a spoofed message that modifies the Forward Information Base (FIB).

2008-06-24 CVE-2008-2427 Buffer Errors vulnerability in Pagesperso-Orange GFL Sdk, Nconvert and Xnview
Stack-based buffer overflow in NConvert 4.92, GFL SDK 2.82, and XnView 1.93.6 on Windows and 1.70 on Linux and FreeBSD allows user-assisted remote attackers to execute arbitrary code via a crafted format keyword in a Sun TAAC file.

2008-01-16 CVE-2008-0122 Numeric Errors vulnerability in ISC Bind
Off-by-one error in the inet_network function in libbind in ISC BIND 9.4.2 and earlier, as used in libc in FreeBSD 6.2 through 7.0-PRERELEASE, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted input that triggers memory corruption.

2007-07-16 CVE-2007-3798 Unchecked Return Value vulnerability in multiple products
Integer overflow in print-bgp.c in the BGP dissector in tcpdump 3.9.6 and earlier allows remote attackers to execute arbitrary code via crafted TLVs in a BGP packet, related to an unchecked return value.

2007-07-14 CVE-2007-3641 Remote vulnerability in Freebsd Libarchive 2.2.3
archive_read_support_format_tar.c in libarchive before 2.2.4 does not properly compute the length of a certain buffer when processing a malformed pax extension header, which allows user-assisted remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted (1) PAX or (2) TAR archive that triggers a buffer overflow.

2006-08-24 CVE-2006-4304 Buffer Overflow vulnerability in NetBSD In-Kernel PPP
Buffer overflow in the sppp driver in FreeBSD 4.11 through 6.1, NetBSD 2.0 through 4.0 beta before 20060823, and OpenBSD 3.8 and 3.9 before 20060902 allows remote attackers to cause a denial of service (panic), obtain sensitive information, and possibly execute arbitrary code via crafted Link Control Protocol (LCP) packets with an option length that exceeds the overall length, which triggers the overflow in (1) pppoe and (2) ippp.

2006-01-19 CVE-2006-0226 Remote Buffer Overflow vulnerability in Freebsd 6.0
Integer overflow in IEEE 802.11 network subsystem (ieee80211_ioctl.c) in FreeBSD before 6.0-STABLE, while scanning for wireless networks, allows remote attackers to execute arbitrary code by broadcasting crafted (1) beacon or (2) probe response frames.
