1 CVE-2007-6150 200 Bypass +Info 2007-11-29 2008-11-15
2.1
None Local Low Not required Partial None None
The "internal state tracking" code for the random and urandom devices in FreeBSD 5.5, 6.1 through 6.3, and 7.0 beta 4 allows local users to obtain portions of previously-accessed random values, which could be leveraged to bypass protection mechanisms that rely on secrecy of those values.
2 CVE-2007-3722 DoS 2007-07-12 2008-11-15
2.1
None Local Low Not required None None Partial
The 4BSD process scheduler in the FreeBSD kernel performs scheduling based on CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service (CPU consumption) by performing voluntary nanosecond sleeps that result in the process not being active during a clock interrupt, as described in "Secretly Monopolizing the CPU Without Superuser Privileges."
3 CVE-2007-3721 DoS 2007-07-12 2008-11-15
2.1
None Local Low Not required None None Partial
The ULE process scheduler in the FreeBSD kernel gives preference to "interactive" processes that perform voluntary sleeps, which allows local users to cause a denial of service (CPU consumption), as described in "Secretly Monopolizing the CPU Without Superuser Privileges."
4 CVE-2007-3645 DoS 2007-07-15 2012-10-29
4.3
None Remote Medium Not required None None Partial
archive_read_support_format_tar.c in libarchive before 2.2.4 allows user-assisted remote attackers to cause a denial of service (crash) via (1) an end-of-file condition within a tar header that follows a pax extension header or (2) a malformed pax extension header in an (a) PAX or a (b) TAR archive, which results in a NULL pointer dereference, a different issue than CVE-2007-3644.
5 CVE-2007-3644 DoS 2007-07-13 2012-10-29
4.3
None Remote Medium Not required None None Partial
archive_read_support_format_tar.c in libarchive before 2.2.4 allows user-assisted remote attackers to cause a denial of service (infinite loop) via (1) an end-of-file condition within a pax extension header or (2) a malformed pax extension header in an (a) PAX or a (b) TAR archive.
6 CVE-2007-3641 DoS Exec Code Overflow 2007-07-13 2012-10-30
9.3
Admin Remote Medium Not required Complete Complete Complete
archive_read_support_format_tar.c in libarchive before 2.2.4 does not properly compute the length of a certain buffer when processing a malformed pax extension header, which allows user-assisted remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted (1) PAX or (2) TAR archive that triggers a buffer overflow.
7 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.
8 CVE-2007-0229 189 DoS Overflow +Priv 2007-01-12 2011-10-11
7.2
Admin Local Low Not required Complete Complete Complete
Integer overflow in the ffs_mountfs function in Mac OS X 10.4.8 and FreeBSD 6.1 allows local users to cause a denial of service (panic) and possibly gain privileges via a crafted DMG image that causes "allocation of a negative size buffer" leading to a heap-based buffer overflow, a related issue to 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.
9 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.
