  • CFNetwork:
    Impact: Restores proper operation of cookies with null expiration times
    Description: This update addresses a non-security regression introduced in Mac OS X 10.5.6. Cookies may not be properly set if a web site attempts to set a session cookie by supplying a null value in the “expires” field, rather than omitting the field. This update addresses the issue by ignoring the “expires” field if it has a null value.
  • CFNetwork:
    Impact: Restores proper operation of session cookies across applications
    Description: This update addresses a non-security regression introduced in Mac OS X 10.5.6. CFNetwork may not save cookies to disk if multiple open applications attempt to set session cookies. This update addresses the issue by ensuring that each application stores its session cookies separately.
  • Certificate Assistant:
    Impact: A local user may manipulate files with the privileges of another user running Certificate Assistant
    Description: An insecure file operation exists in Certificate Assistant’s handling of temporary files. This could allow a local user to overwrite files with the privileges of another user who is running Certificate Assistant. This update addresses the issue through improved handling of temporary files. This issue does not affect systems prior to Mac OS X v10.5. Credit: Apple.
  • ClamAV:
    Impact: Multiple vulnerabilities in ClamAV 0.94
    Description: Multiple vulnerabilities exist in ClamAV 0.94, the most serious of which may lead to arbitrary code execution. This update addresses the issues by updating ClamAV to version 0.94.2.

  • CUPS:
    Impact: Visiting a maliciously crafted website may lead to an unexpected application termination
    Description: Exceeding the maximum number of RSS subscriptions results in a null pointer dereference in the CUPS web interface. This may lead to an unexpected application termination when visiting a maliciously crafted website. In order to trigger this issue, valid user credentials must either be known by the attacker or cached in the user’s web browser. CUPS will be automatically restarted after this issue is triggered. This update addresses the issue by properly handling the number of RSS subscriptions. This issue does not affect systems prior to Mac OS X v10.5.
  • DS Tools:
    Impact: Passwords supplied to dscl are exposed to other local users
    Description: The dscl command-line tool required that passwords be passed to it in its arguments, potentially exposing the passwords to other local users. Passwords exposed include those for users and administrators. This update makes the password parameter optional, and dscl will prompt for the password if needed. Credit: Apple.
  • fetchmail:
    Impact: Multiple vulnerabilities in fetchmail 6.3.8
    Description: Multiple vulnerabilities exist in fetchmail 6.3.8, the most serious of which may lead to a denial of service. This update addresses the issues by updating to version 6.3.9. Further information is available via the fetchmail web site at http://fetchmail.berlios.de/
  • Folder Manager:
    Impact: Other local users may access the Downloads folder
    Description: A default permissions issue exists in Folder Manager. When a user deletes their Downloads folder and Folder Manager recreates it, the folder is created with read permissions for everyone. This update addresses the issue by having Folder Manager limit permissions so that the folder is accessible only to the user. This issue only affects applications using Folder Manager. This issue does not affect systems prior to Mac OS X v10.5. Credit to Graham Perrin of CENTRIM, University of Brighton for reporting this issue.
  • FSEvents:
    Impact: Using the FSEvents framework, a local user may be able to see filesystem activity that would otherwise not be available
    Description: A credential management issue exists in fseventsd. By using the FSEvents framework, a local user may be able to see filesystem activity that would otherwise not be available. This includes the name of a directory which the user would not otherwise be able to see, and the detection of activity in the directory at a given time. This update addresses the issue through improved credential validation in fseventsd. This issue does not affect systems prior to Mac OS X v10.5. Credit to Mark Dalrymple for reporting this issue.
  • Network Time:
    Impact: The Network Time service configuration has been updated
    Description: As a proactive security measure, this update changes the default configuration for the Network Time service. System time and version information will no longer be available in the default ntpd configuration. On Mac OS X v10.4.11 systems, the new configuration takes effect after a system restart when Network Time service is enabled.
  • perl:
    Impact: Using regular expressions containing UTF-8 characters may lead to an unexpected application termination or arbitrary code execution
    Description: A memory corruption issue exists in the handling of certain UTF-8 characters in regular expressions.
