Peron Affects: All FreeBSD 4.x releases since 4.6-RELEASE All FreeBSD 5.x releases prior to 5.4-RELEASE Corrected: 2005-05-06 02:33:46 UTC (RELENG_5, 5.4-STABLE) 2005-05-06 02:34:18 UTC (RELENG_5_4, 5.4-RELEASE) 2005-05-06 02:34:01 UTC (RELENG_5_3, 5.3-RELEASE-p11) 2005-05-06 02:32:54 UTC (RELENG_4, 4.11-STABLE) 2005-05-06 02:33:28 UTC (RELENG_4_11, 4.11-RELEASE-p5) 2005-05-06 02:33:12 UTC (RELENG_4_10, 4.10-RELEASE-p10) CVE Name: CAN-2005-1399 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit . I. Background The iir(4) driver provides support for the Intel Integrated RAID controllers and ICP Vortex RAID controllers. II. Problem Description The default permissions on the /dev/iir device node allow unprivileged local users to open the device and execute ioctl calls. III. Impact Unprivileged local users can send commands to the hardware supported by the iir(4) driver, allowing destruction of data and possible disclosure of data. IV. Workaround Systems without hardware supported by the iir(4) driver are not affected by this issue. On systems which are affected, as a workaround, the permissions on /dev/iir can be changed manually. As root, execute the following command: # chmod 0600 /dev/iir* On 5.x, the following commands are also needed to ensure that the correct permissions are used after rebooting. # echo 'perm iir* 0600' >> /etc/devfs.conf # echo 'devfs_enable="YES"' >> /etc/rc.conf If the administrator has created additional device nodes, or mounted additional instances of devfs(5) elsewhere in the file system name space, attention should be paid to ensure that either the iir device node is not visible in those name spaces, or is similarly protected. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 4-STABLE or 5-STABLE, or to the RELENG_5_3, RELENG_4_11, or RELENG_4_10 security branch dated after the correction date. 2) To patch your present system: The following patches have been verified to apply to FreeBSD 4.10, 4.11, and 5.3 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/patches/SA-05:06/iir.patch # fetch ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/patches/SA-05:06/iir.patch.asc b) Apply the patch. # cd /usr/src # patch < /path/to/patch c) Recompile your kernel as described in and reboot the system.

I. Background 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. II. Problem Description 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. III. Impact Kernel memory may be disclosed to the user process. Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way. For example, a terminal buffer might include a user-entered password. IV. Workaround No workaround is known for i386 and amd64 systems; other platforms are not affected by this issue. V.

I. Background 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. II. Problem Description In several places, variable-length strings were copied into fixed-length buffers without zeroing the unused portion of the buffer. III.
