1 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.
2 CVE-2006-6165 +Priv Bypass 2006-11-28 2008-09-05
7.2
Admin Local Low Not required Complete Complete Complete
** DISPUTED ** ld.so in FreeBSD, NetBSD, and possibly other BSD distributions does not remove certain harmful environment variables, which allows local users to gain privileges by passing certain environment variables to loading processes. NOTE: this issue has been disputed by a third party, stating that it is the responsibility of the application to properly sanitize the environment.
3 CVE-2006-6013 Overflow 2006-11-21 2008-09-05
2.1
None Local Low Not required Partial None None
Integer signedness error in the fw_ioctl (FW_IOCTL) function in the FireWire (IEEE-1394) drivers (dev/firewire/fwdev.c) in various BSD kernels, including DragonFlyBSD, FreeBSD 5.5, MidnightBSD 0.1-CURRENT before 20061115, NetBSD-current before 20061116, NetBSD-4 before 20061203, and TrustedBSD, allows local users to read arbitrary memory contents via certain negative values of crom_buf->len in an FW_GCROM command. NOTE: this issue has been labeled as an integer overflow, but it is more like an integer signedness error.
4 CVE-2006-5824 DoS Overflow 2006-11-09 2008-09-05
4.9
None Local Low Not required None None Complete
Integer overflow in the ffs_rdextattr function in FreeBSD 6.1 allows local users to cause a denial of service (kernel panic) and trigger a heap-based buffer overflow via a crafted UFS filesystem, a different vulnerability than CVE-2006-5679. NOTE: a third party states that this issue does not cross privilege boundaries in FreeBSD because only root may mount a filesystem.
5 CVE-2006-5680 DoS 2006-11-08 2008-09-05
5.0
None Remote Low Not required None None Partial
The libarchive library in FreeBSD 6-STABLE after 2006-09-05 and before 2006-11-08 allows context-dependent attackers to cause a denial of service (CPU consumption) via a malformed archive that causes libarchive to skip a region past the actual end of the archive, which triggers an infinite loop that attempts to read more data.
6 CVE-2006-5679 189 DoS Exec Code Overflow 2006-11-03 2011-10-11
4.6
None Local Low Not required Partial Partial Partial
Integer overflow in the ffs_mountfs function in FreeBSD 6.1 allows local users to cause a denial of service (panic) and possibly execute arbitrary code via a crafted UFS filesystem that causes invalid or large size parameters to be provided to the kmem_alloc function. NOTE: a third party states that this issue does not cross privilege boundaries in FreeBSD because only root may mount a filesystem.
7 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.
8 CVE-2006-5483 DoS 2006-10-24 2008-09-05
2.1
None Local Low Not required None None Partial
p1003_1b.c in FreeBSD 6.1 allows local users to cause an unspecified denial of service by setting a scheduler policy, which should only be settable by root.
9 CVE-2006-5482 DoS 2006-10-24 2008-09-05
2.1
None Local Low Not required None None Partial
ufs_vnops.c in FreeBSD 6.1 allows local users to cause an unspecified denial of service by calling the ftruncate function on a file type that is not VREG, VLNK or VDIR, which is not defined in POSIX.
10 CVE-2006-4516 DoS Mem. Corr. 2006-10-11 2008-09-05
4.9
None Local Low Not required None None Complete
Integer signedness error in FreeBSD 6.0-RELEASE allows local users to cause a denial of service (memory corruption and kernel panic) via a PT_LWPINFO ptrace command with a large negative data value that satisfies a signed maximum value check but is used in an unsigned copyout function call.
11 CVE-2006-4304 DoS Exec Code Overflow +Info 2006-08-23 2008-09-05
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.
12 CVE-2006-4178 DoS 2006-09-25 2008-09-05
4.9
None Local Low Not required None None Complete
Integer signedness error in the i386_set_ldt call in FreeBSD 5.5, and possibly earlier versions down to 5.2, allows local users to cause a denial of service (crash) via unspecified arguments that use negative signed integers to cause the bzero function to be called with a large length parameter, a different vulnerability than CVE-2006-4172.
13 CVE-2006-4172 DoS Exec Code Overflow 2006-09-25 2008-09-05
7.2

6.4
None Remote Low Not required Partial Partial None
The build process for ypserv in FreeBSD 5.3 up to 6.1 accidentally disables access restrictions when using the /var/yp/securenets file, which allows remote attackers to bypass intended access restrictions.
15 CVE-2006-2654 Dir. Trav. 2006-06-01 2008-09-05
6.4
None Remote Low Not required Partial Partial None
Directory traversal vulnerability in smbfs smbfs on FreeBSD 4.10 up to 6.1 allows local users to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences. NOTE: this is similar to CVE-2006-1864, but this is a different implementation of smbfs, so it has a different CVE identifier.
16 CVE-2006-1283 +Priv 2006-03-23 2011-08-25
7.2
Admin Local Low Not required Complete Complete Complete
opiepasswd in One-Time Passwords in Everything (OPIE) in FreeBSD 4.10-RELEASE-p22 through 6.1-STABLE before 20060322 uses the getlogin function to determine the invoking user account, which might allow local users to configure OPIE access to the root account and possibly gain root privileges if a root shell is permitted by the configuration of the wheel group or sshd.
17 CVE-2006-1056 310 +Info 2006-04-20 2012-03-19
2.1
None Local Low Not required Partial None None
The Linux kernel before 2.6.16.9 and the FreeBSD kernel, when running on AMD64 and other 7th and 8th generation AuthenticAMD processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one process to determine portions of the state of floating point instructions of other processes, which can be leveraged to obtain sensitive information such as cryptographic keys. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processers in a security-relevant fashion that was not addressed by the kernels.
18 CVE-2006-0905 2006-03-23 2008-09-05
7.5
User Remote Low Not required Partial Partial Partial
A "programming error" in fast_ipsec in FreeBSD 4.8-RELEASE through 6.1-STABLE and NetBSD 2 through 3 does not properly update the sequence number associated with a Security Association, which allows packets to pass sequence number checks and allows remote attackers to capture IPSec packets and conduct replay attacks.
19 CVE-2006-0900 DoS 2006-02-27 2008-09-10
