DATE CVE VULNERABILITY TITLE RISK
2011-08-19 CVE-2011-2895 Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products
The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896.

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).
9.3
2008-09-11 CVE-2008-3584 Improper Input Validation vulnerability in Netbsd 3.0/3.1/4.0
NetBSD 3.0, 3.1, and 4.0, when a pppoe instance exists, does not properly check the length of a PPPoE packet tag, which allows remote attackers to cause a denial of service (system crash) via a crafted PPPoE packet.

2008-03-13 CVE-2008-1335 Unspecified vulnerability in Netbsd and Netbsd Current
The ipsec4_get_ulp function in the kernel in NetBSD 2.0 through 3.1 and NetBSD-current before 20071028, when the fast_ipsec subsystem is enabled, allows remote attackers to bypass the IPsec policy by sending packets from a source machine with a different endianness than the destination machine, a different vulnerability than CVE-2006-0905.

2006-12-20 CVE-2006-6652 Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products
Buffer overflow in the glob implementation (glob.c) in libc in NetBSD-current before 20050914, NetBSD 2.* and 3.* before 20061203, and Apple Mac OS X before 2007-004, as used by the FTP daemon and tnftpd, allows remote authenticated users to execute arbitrary code via a long pathname that results from path expansion.

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.

2003-08-27 CVE-2003-0466 Off-by-one Error vulnerability in multiple products
Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.

Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.

Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3.
