CVE-ID: CAN-2005-1344
Available for: Mac OS X Server v10.3.9
Impact: The htdigest program contains a buffer overflow, which, if used improperly in a CGI application, could allow a remote system compromise.
Description: The htdigest program contains a buffer overflow, and could be used in a CGI application to manage user access controls to a web server. This update fixes the buffer overflow in htdigest. Apple does not provide any CGI applications that use the htdigest program. Apache 2 ships only with Mac OS X Server, and is off by default. This issue was fixed for Apache 1.3 in Security Update 2005-005. Credit to JxT of SNOsoft for reporting this issue.
CVE-ID: CAN-2004-0942, CAN-2004-0885
Available for: Mac OS X Server v10.3.9
Impact: Multiple security issues in Apache 2.
Description: The Apache Group fixed two vulnerabilities between versions 2.0.52 and 2.0.53 (the Apache Group security page for Apache 2 is located at http://httpd.apache.org/security/vulnerabilities_20.html). Apache 2 is updated to version 2.0.53 (the previous version was 2.0.52). Apache 2 ships only with Mac OS X Server, and is off by default.
CVE-ID: CAN-2004-1083, CAN-2004-1084
Available for: Mac OS X Server v10.3.9, Mac OS X Server v10.4.2
Impact: Apache 2 example configurations do not fully block access to resource forks, ".ht" files, or ".DS_Store" files.
Description: Apache 2 ships only with Mac OS X Server, and is off by default. It is important that administrators who enable this server manually are aware of the files that should be blocked to avoid security exposures. A default Apache 2 configuration blocks access to files starting with ".ht" in a case-sensitive way. The Apple HFS+ filesystem isn't case-sensitive when performing file access, and maps resource forks of files to path names. The Finder may also create .DS_Store files containing the names of files in locations used to serve webpages. This update modifies the sample Apache 2 configuration to show how to restrict access to these files and resource forks. This issue was fixed for Apache 1.3 in Security Update 2004-12-02. Additional information is available here.
CVE-ID: CAN-2005-2501
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.2, Mac OS X Server v10.4.2
Impact: Opening a malicious, rich text file could lead to arbitrary code execution.
Description: A buffer overflow in the handling of maliciously crafted rich text files could lead to arbitrary code execution. This update prevents the buffer overflow from occurring.
CVE-ID: CAN-2005-2502
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.2, Mac OS X Server v10.4.2
Impact: Opening a maliciously crafted Microsoft Word .doc file could result in arbitrary code execution.
Description: A buffer overflow in AppKit that is responsible for reading Word documents could allow arbitrary code execution. Only applications such as TextEdit that use AppKit to open Word documents are vulnerable. Microsoft Word for Mac OS X is not vulnerable. This update prevents the buffer overflow.
CVE-ID: CAN-2005-2503
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.2, Mac OS X Server v10.4.2

Description: A malicious user who has full physical access to a system could create additional accounts by forcing an error condition. This update prevents the error conditions from occurring at the login window.
CVE-ID: CAN-2005-2504
Available for: Mac OS X v10.4.2, Mac OS X Server v10.4.2
Impact: The System Profiler information about whether or not a Bluetooth device requires authentication is misleading.
Description: Selecting "Require pairing for security" in Bluetooth preferences correctly sets the device to require authentication, but in System Profiler the device is labeled with "Requires Authentication: No." This update changes System Profiler to accurately reflect the Bluetooth security settings. This issue does not affect systems prior to Mac OS X 10.4. Credit to John M. Glenn of San Francisco for reporting this issue.
CVE-ID: CAN-2005-2505
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9

CVE-ID: CAN-2005-2506
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.2, Mac OS X Server v10.4.2
Impact: Passing a malformed date to the CoreFoundation framework can cause applications to stall.
Description: The parsing of Gregorian dates in the CoreFoundation framework is vulnerable to an algorithmic complexity attack that could result in a denial of service. This update modifies the algorithm to parse all valid dates within a fixed processing time. Credit to David Remahl of www.remahl.se/david for reporting this issue.
CVE-ID: CAN-2005-2525, CAN-2005-2526
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.2, Mac OS X Server v10.4.2
Impact: The CUPS printing service will not print unless it is restarted.
Description: When handling multiple, simultaneous, print jobs, the CUPS printing service can stop printing because it incorrectly tracks open file descriptors. In addition, if CUPS receives a partial IPP request and a client terminates the connection, the printing service will then consume all available CPUs. If the service is restarted, then printing will resume. This update corrects the handling of multiple, simultaneous print jobs and partial requests.

CVE-ID: CAN-2005-2512
Available for: Mac OS X v10.4.2, Mac OS X Server v10.4.2
Impact: Loss of privacy due to Mail loading remote images in HTML emails.
Description: When Mail.app is used to print or forward an HTML message, it will attempt to load remote images even if a user's preferences disallow it. As this network traffic is not expected, it may be considered a privacy leak. This update addresses the issue by having Mail.app only load remote images in HTML messages when the preferences allow it. This issue does not affect systems prior to Mac OS X v10.4. Credit to Brad Miller of CynicalPeak and John Pell of Foreseeable Solutions for reporting this issue.

Available for: Mac OS X v10.4.2, Mac OS X Server v10.4.2
Impact: Recently-used passwords are visible via the password assistant.
Description: The password assistant provides an easy mechanism for selecting a good password. If an administrator uses the password assistant while adding multiple accounts, they will be able to view previously suggested passwords. This only occurs when password assistant is used more than once from the same process. This update addresses the issue by resetting the suggested password list each time the password assistant is displayed. This issue does not affect systems prior to Mac OS X v10.4. Credit to Andrew Langmead of Boston.com for reporting this issue.
