11 Jan 2006 — The ispell_op function in ee on FreeBSD 4.10 to 6.0 uses predictable filenames and does not confirm which file is being written, which allows local users to overwrite arbitrary files via a symlink attack when ee invokes ispell. The ispell_op function used by ee(1) while executing spell check operations employs an insecure method of temporary file generation. This method produces predictable file names based on the process ID and fails to confirm which path will be over written with the user. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:02.ee.asc •

31 Dec 2005 — 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. • https://packetstorm.news/files/id/42925 •

30 Jun 2005 — FreeBSD 4.x through 4.11 and 5.x through 5.4 allows remote attackers to modify certain TCP options via a TCP packet with the SYN flag set for an already established session. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:15.tcp.asc •

31 May 2005 — Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. • https://www.exploit-db.com/exploits/1008 •

06 May 2005 — FreeBSD 4.6 to 4.11 and 5.x to 5.4 uses insecure default permissions for the /dev/iir device, which allows local users to execute restricted ioctl calls to read or modify data on hardware that is controlled by the iir driver. The default permissions on the /dev/iir device node allow unprivileged local users to open the device and execute ioctl calls. Unprivileged local users can send commands to the hardware supported by the iir(4) driver, allowing destruction of data and possible disclosure of data. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:06.iir.asc •

06 May 2005 — The kernel in FreeBSD 4.x to 4.11 and 5.x to 5.4 does not properly clear certain fixed-length buffers when copying variable-length data for use by applications, which could allow those applications to read previously used sensitive memory. In many parts of the FreeBSD kernel, names (of mount points, devices, files, etc.) are manipulated as NULL-terminated strings, but are provided to applications within fixed-length buffers. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:08.kmem.asc •

06 May 2005 — The i386_get_ldt system call in FreeBSD 4.7 to 4.11 and 5.x to 5.4 allows local users to access sensitive kernel memory via arguments with negative or very large values. The i386_get_ldt(2) system call allows a process to request that a portion of its Local Descriptor Table be copied from the kernel into userland. The i386_get_ldt(2) syscall performs insufficient validation of its input arguments. In particular, negative or very large values may allow inappropriate data to be copied from the kernel. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:07.ldt.asc •

15 Apr 2005 — The SIOCGIFCONF ioctl (ifconf function) in FreeBSD 4.x through 4.11 and 5.x through 5.4 does not properly clear a buffer before using it, which allows local users to obtain portions of sensitive kernel memory. Flaws for Finder, Software Update, memberd, Keychain, and the kernel have all been addressed in this latest Apple update. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:04.ifconf.asc • CWE-399: Resource Management Errors •

12 Apr 2005 — Multiple symlink vulnerabilities in portupgrade before 20041226_2 in FreeBSD allow local users to (1) overwrite arbitrary files and possibly replace packages to execute arbitrary code via pkg_fetch, (2) overwrite arbitrary files via temporary files when portupgrade upgrades a port or package, or (3) create arbitrary zero-byte files via the pkgdb.fixme temporary file. • http://secunia.com/advisories/14903 •

06 Apr 2005 — Race condition in gzip 1.2.4, 1.3.3, and earlier, when decompressing a gzipped file, allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by gzip after the decompression is complete. The gzip and gunzip programs are vulnerable to a race condition when setting file permissions (CVE-2005-0988), as well as improper handling of filename restoration (CVE-2005-1228). The zgrep utility improperly sanitizes argumen... • ftp://ftp.sco.com/pub/updates/UnixWare/SCOSA-2005.58/SCOSA-2005.58.txt •
