6.9
 None Local Medium Not required Complete Complete Complete
sys/nfsclient/nfs_vfsops.c in the NFS client in the kernel in FreeBSD 7.2 through 8.1-PRERELEASE, when vfs.usermount is enabled, does not validate the length of a certain fhsize parameter, which allows local users to gain privileges via a crafted mount request.
5 CVE-2010-0318 264 2010-01-15 2011-08-08
6.9
 None Local Medium Not required Complete Complete Complete
The replay functionality for ZFS Intent Log (ZIL) in FreeBSD 7.1, 7.2, and 8.0, when creating files during replay of a setattr transaction, uses 7777 permissions instead of the original permissions, which might allow local users to read or modify unauthorized files in opportunistic circumstances after a system crash or power failure.
6 CVE-2009-3527 362 DoS +Priv Mem. Corr. 2009-10-06 2009-10-07
6.9
 Admin Local Medium Not required Complete Complete Complete
Race condition in the Pipe (IPC) close function in FreeBSD 6.3 and 6.4 allows local users to cause a denial of service (crash) or gain privileges via vectors related to kqueues, which triggers a use after free, leading to a NULL pointer dereference or memory corruption.
7 CVE-2009-0689 119 DoS Exec Code Overflow 2009-07-01 2010-11-15
6.8
 User Remote Medium Not required Partial Partial Partial
Array index error in the (1) dtoa implementation in dtoa.c (aka pdtoa.c) and the (2) gdtoa (aka new dtoa) implementation in gdtoa/misc.c in libc, as used in multiple operating systems and products including in FreeBSD 6.4 and 7.2, NetBSD 5.0, OpenBSD 4.5, Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4, K-Meleon 1.5.3, SeaMonkey 1.1.8, and other products, allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large precision value in the format argument to a printf function, which triggers incorrect memory allocation and a heap-based buffer overflow during conversion to a floating-point number.
8 CVE-2008-5162 310 2008-11-26 2008-12-03
6.9
 None Local Medium Not required Complete Complete Complete
The arc4random function in the kernel in FreeBSD 6.3 through 7.1 does not have a proper entropy source for a short time period immediately after boot, which makes it easier for attackers to predict the function's return values and conduct certain attacks against the GEOM framework and various network protocols, related to the Yarrow random number generator.
9 CVE-2008-5142 59 2008-11-18 2012-10-30
6.9
 None Local Medium Not required Complete Complete Complete
sendbug in freebsd-sendpr 3.113+5.3 on Debian GNU/Linux allows local users to overwrite arbitrary files via a symlink attack on a /tmp/pr.##### temporary file.
10 CVE-2008-3531 119 Overflow +Priv 2008-09-05 2008-09-24
6.9
 None Local Medium Not required Complete Complete Complete
Stack-based buffer overflow in sys/kern/vfs_mount.c in the kernel in FreeBSD 7.0 and 7.1, when vfs.usermount is enabled, allows local users to gain privileges via a crafted (1) mount or (2) nmount system call, related to copying of "user defined data" in "certain error conditions."
11 CVE-2008-0217 264 2008-01-15 2008-09-05
6.9
 None Local Medium Not required Complete Complete Complete
The script program in FreeBSD 5.0 through 7.0-PRERELEASE invokes openpty, which creates a pseudo-terminal with world-readable and world-writable permissions when it is not run as root, which allows local users to read data from the terminal of the user running script.
12 CVE-2007-0267 399 DoS 2007-01-16 2011-06-10
6.6
 None Local Low Not required None Complete Complete
The ufs_lookup function in the Mac OS X 10.4.8 and FreeBSD 6.1 kernels allows local users to cause a denial of service (kernel panic) and possibly corrupt other filesystems by mounting a crafted UNIX File System (UFS) DMG image that contains a corrupted directory entry (struct direct), related to the ufs_dirbad function. NOTE: a third party states that the FreeBSD issue does not cross privilege boundaries.
13 CVE-2007-0166 2007-01-11 2008-11-15
6.6
 Admin Local Medium Single system Complete Complete Complete
The jail rc.d script in FreeBSD 5.3 up to 6.2 does not verify pathnames when writing to /var/log/console.log during a jail start-up, or when file systems are mounted or unmounted, which allows local root users to overwrite arbitrary files, or mount/unmount files, outside of the jail via a symlink attack.
14 CVE-2006-2655 Bypass 2006-06-01 2008-09-05
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-2003-1230 2003-12-31 2008-09-05
6.4
 None Remote Low Not required Partial Partial None
The implementation of SYN cookies (syncookies) in FreeBSD 4.5 through 5.0-RELEASE-p3 uses only 32-bit internal keys when generating syncookies, which makes it easier for remote attackers to conduct brute force ISN guessing attacks and spoof legitimate traffic.
17 CVE-2001-1185 +Priv 2001-12-10 2008-09-05
6.2
 Admin Local High Not required Complete Complete Complete
Some AIO operations in FreeBSD 4.4 may be delayed until after a call to execve, which could allow a local user to overwrite memory of the new process and gain privileges.
18 CVE-2001-1145 2001-08-17 2008-09-10
6.2
 Admin Local High Not required Complete Complete Complete
fts routines in FreeBSD 4.3 and earlier, NetBSD before 1.5.2, and OpenBSD 2.9 and earlier can be forced to change (chdir) into a different directory than intended when the directory above the current directory is moved, which could cause scripts to perform dangerous actions on the wrong directories.
19 CVE-2001-0371 2001-06-18 2008-09-05
6.2
 None Local High Not required Complete Complete Complete
Race condition in the UFS and EXT2FS file systems in FreeBSD 4.2 and earlier, and possibly other operating systems, makes deleted data available to user processes before it is zeroed out, which allows a local user to access otherwise restricted information.

6.2
 Admin Local High Not required Complete Complete Complete
The BSD make program allows local users to modify files via a symlink attack when the -j option is being used.
