1 CVE-2006-6730 2006-12-26 2008-09-05
6.6
None Local Medium Single system Complete Complete Complete
OpenBSD and NetBSD permit usermode code to kill the display server and write to the X.Org /dev/xf86 device, which allows local users with root privileges to reduce securelevel by replacing the System Management Mode (SMM) handler via a write to an SMRAM address within /dev/xf86 (aka the video card memory-mapped I/O range), and then launching the new handler via a System Management Interrupt (SMI), as demonstrated by a write to Programmed I/O port 0xB2.
2 CVE-2006-6397 Overflow 2006-12-07 2008-09-05
4.4
User Local Medium Not required Partial Partial Partial
** DISPUTED ** Integer overflow in banner/banner.c in FreeBSD, NetBSD, and OpenBSD might allow local users to modify memory via a long banner. NOTE: CVE and multiple third parties dispute this issue. Since banner is not setuid, an exploit would not cross privilege boundaries in normal operations. This issue is not a vulnerability.
3 CVE-2006-6164 +Priv 2006-11-28 2017-07-28
7.2
Admin Local Low Not required Complete Complete Complete
The _dl_unsetenv function in loader.c in the ELF ld.so in OpenBSD 3.9 and 4.0 does not properly remove duplicate environment variables, which allows local users to pass dangerous variables such as LD_PRELOAD to loading processes, which might be leveraged to gain privileges.
4 CVE-2006-5550 DoS 2006-10-26 2008-09-05
4.9
None Local Low Not required None None Complete
The kernel in FreeBSD 6.1 and OpenBSD 4.0 allows local users to cause a denial of service via unspecified vectors involving certain ioctl requests to /dev/crypto.
5 CVE-2006-5218 DoS Overflow +Priv 2006-10-10 2017-07-19
4.6
User Local Low Not required Partial Partial Partial
Integer overflow in the systrace_preprepl function (STRIOCREPLACE) in systrace in OpenBSD 3.9 and NetBSD 3 allows local users to cause a denial of service (crash), gain privileges, or read arbitrary kernel memory via large numeric arguments to the systrace ioctl.
6 CVE-2006-4436 Bypass 2006-08-28 2017-07-19
5.0
None Remote Low Not required Partial None None
isakmpd in OpenBSD 3.8, 3.9, and possibly earlier versions, creates Security Associations (SA) with a replay window of size 0 when isakmpd acts as a responder during SA negotiation, which allows remote attackers to replay IPSec packets and bypass the replay protection.
7 CVE-2006-4435 DoS 2006-08-28 2017-07-19
4.9
None Local Low Not required None None Complete
OpenBSD 3.8, 3.9, and possibly earlier versions allows context-dependent attackers to cause a denial of service (kernel panic) by allocating more semaphores than the default.
8 CVE-2006-4304 DoS Exec Code Overflow +Info 2006-08-23 2017-07-19
10.0
Admin Remote Low Not required Complete Complete Complete
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. NOTE: this issue was originally incorrectly reported for the ppp driver.
9 CVE-2006-0098 2006-01-06 2008-09-05
4.6
None Local Low Not required Partial Partial Partial
The dupfdopen function in sys/kern/kern_descrip.c in OpenBSD 3.7 and 3.8 allows local users to re-open arbitrary files by using setuid programs to access file descriptors using /dev/fd/.
