DATE CVE VULNERABILITY TITLE RISK
2007-01-18 CVE-2007-0343 Remote Denial Of Service vulnerability in OpenBSD ICMP6 Echo Request
OpenBSD before 20070116 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via certain IPv6 ICMP (aka ICMP6) echo request packets.

2005-12-31 CVE-2005-4351 Local Security vulnerability in kernel
The securelevels implementation in FreeBSD 7.0 and earlier, OpenBSD up to 3.8, DragonFly up to 1.2, and Linux up to 2.6.15 allows root users to bypass immutable settings for files by mounting another filesystem that masks the immutable files while the system is running.

2005-01-13 CVE-2005-0740 Remote Denial Of Service vulnerability in OpenBSD TCP Timestamp
The TCP stack (tcp_input.c) in OpenBSD 3.5 and 3.6 allows remote attackers to cause a denial of service (system panic) via crafted values in the TCP timestamp option, which causes invalid arguments to be used when calculating the retransmit timeout.

2004-05-04 CVE-2004-0220 Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in Openbsd
isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service via an ISAKMP packet with a malformed Cert Request payload, which causes an integer underflow that is used in a malloc operation that is not properly handled, as demonstrated by the Striker ISAKMP Protocol Test Suite.

2004-05-04 CVE-2004-0219 Unspecified vulnerability in Openbsd
isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service (crash) via an ISAKMP packet with a malformed IPSEC SA payload, as demonstrated by the Striker ISAKMP Protocol Test Suite.

2004-05-04 CVE-2004-0218 Denial Of Service vulnerability in OpenBSD ISAKMPD Zero Payload Length
isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service (infinite loop) via an ISAKMP packet with a zero-length payload, as demonstrated by the Striker ISAKMP Protocol Test Suite.

2004-03-03 CVE-2004-0114 Privilege Escalation vulnerability in BSD Kernel SHMAT System Call
The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges.

2003-12-31 CVE-2003-1366 Information Exposure vulnerability in Openbsd
chpass in OpenBSD 2.0 through 3.2 allows local users to read portions of arbitrary files via a hard link attack on a temporary file used to store user database information.

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.

2003-03-31 CVE-2003-0144 Local Buffer Overflow vulnerability in Multiple Vendor LPRM
Buffer overflow in the lprm command in the lprold lpr package on SuSE 7.1 through 7.3, OpenBSD 3.2 and earlier, and possibly other operating systems, allows local users to gain root privileges via long command line arguments such as (1) request ID or (2) user name.
