  • AppKit
    CVE-ID: CAN-2004-1308, CAN-2004-1307
    CERT: VU#125598, VU#539110
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: An integer overflow in the handling of TIFF files could permit arbitrary code execution.
    Description: A malformed TIFF image could contain parameters that result in image data overwriting the heap. This issue has been addressed by adding additional tests when calculating the space needed for an image.

  • AppKit
    CVE-ID: CAN-2005-1330
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: A Cocoa application will quit through an unhandled exception from NXSeek().
    Description: A malformed TIFF image can cause a call to NXSeek() with an offset outside the image. This raises an exception which is not handled. The default handler then causes the application to exit. This update causes an error to be returned to the application. Credit to Henrik Dalgaard of Echo One for reporting this issue.

  • AppleScript
    CVE-ID: CAN-2005-1331
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Scripts created using the applescript: URI mechanism could display code differently than that which would actually run.
    Description: The applescript: URI mechanism is a feature that allows AppleScript code to be distributed via a hyperlink. When an applescript: URI is clicked, the AppleScript Editor opens and displays the code that has been downloaded. If the code is then compiled and run, it may not execute exactly as it is displayed. This issue has been addressed by rejecting URIs containing characters that could be used to mislead the user. Credit to David Remahl of www.remahl.se/david for reporting this issue.

  • Bluetooth
    CVE-ID: CAN-2005-1332
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Bluetooth-enabled systems may allow file exchange without prompting users.
    Description: The Bluetooth file exchange service is enabled by default on systems with Bluetooth capability. This could allow files to be shared without properly notifying the user. In addition, the default directory for file sharing may be used by other applications, leading to unintentional file sharing. Security Update 2005-005 disables Bluetooth file exchange and changes the location of the default transfer directory on systems where the old default directory is set. In addition, new users of a system must now enable Bluetooth file exchange before it is allowed. Users with Bluetooth-enabled systems should read this article for more information on the changes provided by this update. Credit to kf_lists[at]digitalmunition[dot]com for reporting this issue.

  • Bluetooth
    CVE-ID: CAN-2005-1333
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Directory traversal via Bluetooth file and object exchange.
    Description: Due to insufficient input checking, the Bluetooth file and object exchange services could be used to access files outside of the default file exchange directory. Security Update 2005-005 addresses this issue by adding enhanced filtering for path-delimiting characters. Credit to kf_lists[at]digitalmunition[dot]com for reporting this issue.

  • Directory Services
    CVE-ID: CAN-2005-1335
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: chfn/chpass/chsh could be manipulated to give privileges to an unprivileged user.
    Description: chfn/chpass/chsh is a hard-linked set of SUID programs. Certain code paths use external helper programs in an insecure manner which could lead to a privilege escalation. This update provides secure mechanisms for running helper programs.

  • Finder
    CVE-ID: CAN-2005-0342
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Unsafe handling of .DS_Store files could be used by local attackers to overwrite files and lead to privilege escalation.
    Description: Finder uses .DS_Store files to store and retrieve information used to display folders on the system. When writing these files, Finder could follow a link resulting in the overwrite of an arbitrary file. In addition, these files could contain data supplied by malicious users, allowing them to gain privileges by altering system configuration files. Security Update 2005-005 addresses this issue by updating Finder to check that .DS_Store files are not links before writing to them.

  • Foundation
    CVE-ID: CAN-2005-1336
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Buffer overflow via an environment variable for applications using the Foundation framework.
    Description: The incorrect handling of an environment variable within the Foundation framework can result in a buffer overflow that may be used to execute arbitrary code. This issue has been addressed by improved handling of the environment variable.

  • Help Viewer
    CVE-ID: CAN-2005-1337
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Help Viewer could be used to run Javascript without the restrictions normally imposed.
    Description: When Javascript is loaded for a remote site, it is executed in a restricted environment. The environment restrictions are not applied for local Javascript files loaded by the Help Viewer. Security Update 2005-005 addresses this by only allowing Help Viewer to load registered pages. Credit to David Remahl of www.remahl.se/david for reporting this issue.

  • LDAP
    CVE-ID: CAN-2005-1338
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Passwords could initially be stored into LDAP in plain text when using an LDAP server not running on Mac OS X.
    Description: When a system is bound to an LDAP server that has "ldap_extended_operation" disabled or not supported, and new accounts are created using the Workgroup Manager, then the initial password can be stored in the clear. If the password is modified using the Inspector, it will be correctly stored in a hashed form. This issue does not occur when using the Apple supplied Open Directory server. For servers not supporting "ldap_extended_operation," this update now stores new passwords in the hashed form.

  • libXpm
    CVE ID: CAN-2004-0687 CERT: VU#882750
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: A vulnerability in the parsing of malformed XPM files could allow arbitrary code execution.
    Description: The xpmParseColors() function in the XFree86 libXpm library contains a vulnerability in the parsing of malformed image files that may lead to a stack overflow, and could allow arbitrary code execution. Images downloaded via a web browser may use the XPM format and allow remote exploitability. libXpm is not installed by default on Mac OS X or Mac OS X Server systems. It is an optional install item via the X11 package. Credit to Chris Evans <chris@scary.beasts.org> for reporting this issue.

  • libXpm
    CVE ID: CAN-2004-0688 CERT: VU#537878

    Impact: A vulnerability in the parsing of malformed XPM files could allow arbitrary code execution.
    Description: Multiple libXpm routines contain integer overflow vulnerabilities that may allow an attacker to cause a denial-of-service condition or execute arbitrary code. Images downloaded via a web browser may use the XPM format and allow remote exploitability. libXpm is not installed by default on Mac OS X or Mac OS X Server systems. It is an optional install item via the X11 package. Credit to Chris Evans <chris@scary.beasts.org> for reporting this issue.

  • lukemftpd
    CVE-ID: CAN-2005-1339
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: When using the chroot feature of ftp, users can bypass the restriction by using their full name.
    Description: The ftp server allows users to login with either their full name or their short name. In order to restrict users to their home directory, all permitted login names must be listed in /etc/ftpchroot. Users are permitted to change their full name. This issue has been addressed by mapping full names to short names before checking the /etc/ftpchroot restriction list. Credit to Rob Griffiths of macosxhints.com for reporting this issue.

  • NetInfo
    CVE-ID: CAN-2005-0594
    Available for: Mac OS X Server v10.3.9
    Impact: The Netinfo Setup Tool (NeST) contains a buffer overflow that could permit arbitrary code execution.
    Description: NeST is a SUID tool. It contains a buffer overflow that could permit arbitrary code execution. This update prevents the buffer overflow from occurring. Credit to iDEFENSE Labs for reporting this issue.

  • Server Admin
    CVE-ID: CAN-2005-1340
    Available for: Mac OS X Server v10.3.9
    Impact: Enabling the HTTP proxy service also enables it for users not on your network if there are no access restrictions.
    Description: When the HTTP proxy service is enabled in Server Admin, it does not restrict which networks can access it. If there are no external access controls, then users on the Internet can also use the proxy. The HTTP proxy service is disabled by default. This update adds a user interface component to Server Admin, which allows the HTTP proxy to be restricted to local networks.

  • sudo
    CVE-ID: CAN-2004-1051
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Bash scripts run via sudo can be subverted.
    Description: Sudo versions prior to 1.6.8p2 do not properly sanitize their environment. A malicious local user with permission to run a bash shell script could exploit this to run arbitrary commands. Apple does not provide any pre-authorized bash shell scripts by default. This issue is addressed by removing bash shell functions from the environment before running subsequent commands.

  • Terminal
    CVE-ID: CAN-2005-1341 CERT: VU#994510
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Malicious input could cause data to be inserted into a user's Terminal command line.
    Description: The Terminal utility allows window titles to be read as input via a particular escape sequence. This could allow malicious content to inject data when it is displayed in a Terminal session. Security Update 2005-005 addresses the issue by removing handlers for this insecure escape sequence. Credit to David Remahl of www.remahl.se/david for reporting this issue.

  • Terminal
    CVE-ID: CAN-2005-1342 CERT: VU#356070
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: Escape characters embedded in x-man-page URIs could insert commands into a user's Terminal session.
    Description: The x-man-page URI scheme provides support for displaying manual pages via the Terminal utility. Insufficient validation of these URIs can allow data to be inserted in a Terminal session. Security Update 2005-005 addresses this by adding escape sequence validation to the URI handler. Credit to David Remahl of www.remahl.se/david for reporting this issue.

  • VPN
    CVE-ID: CAN-2005-1343
    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
    Impact: A local user can obtain root privileges if the system is
    being used as a VPN server.
    Description: A buffer overflow in "vpnd" could be used by a local user to obtain root privileges if the system is configured as a VPN server.
