CoreTypes CVE-ID: CVE-2008-4234 Available for: Mac OS X v10.5 through v10.5.5, Mac OS X Server v10.5 through v10.5.5 Impact: Attempting to launch unsafe downloaded content may not lead to a warning Description: Mac OS X provides the Download Validation capability to indicate potentially unsafe files. Applications such as Safari and others use Download Validation to help warn users prior to launching files marked as potentially unsafe. This update adds to the list of potentially unsafe types. It adds the content type for files that have executable permissions and no specific application association. These files are potentially unsafe as they will launch in Terminal and their content will be executed as commands. While these files are not automatically launched, if manually opened they could lead to the execution of arbitrary code. This issue does not affect systems prior to Mac OS X v10.5. Flash Player Plug-in CVE-ID: CVE-2008-4818, CVE-2008-4819, CVE-2008-4820, CVE-2008-4821, CVE-2008-4822, CVE-2008-4823, CVE-2008-4824 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.5, Mac OS X Server v10.5 through v10.5.5 Impact: Multiple vulnerabilities in Adobe Flash Player plug-in Description: Multiple issues exist in the Adobe Flash Player plug- in, the most serious of which may lead to arbitrary code execution when viewing a maliciously crafted web site. The issues are addressed by updating the Flash Player plug-in to version 9.0.151.0. Further information is available via the Adobe web site at http://www.adobe.com/support/security/bulletins/apsb08-20.html Kernel CVE-ID: CVE-2008-4218 Available for: Mac OS X v10.5 through v10.5.5, Mac OS X Server v10.5 through v10.5.5 Impact: A local user may obtain system privileges Description: Integer overflow issues exist within the i386_set_ldt and i386_get_ldt system calls, which may allow a local user to execute arbitrary code with system privileges. This update addresses the issues through improved bounds checking. These issues do not affect PowerPC systems. Credit to Richard Vaneeden of IOActive, Inc. for reporting these issues. Kernel CVE-ID: CVE-2008-4219 Available for: Mac OS X v10.5 through v10.5.5, Mac OS X Server v10.5 through v10.5.5 Impact: Running an executable that links dynamic libraries on an NFS share may lead to an unexpected system shutdown Description: An infinite loop may occur when a program located on an NFS share receives an exception. This may lead to an unexpected system shutdown. This update addresses the issue through improved handling of exceptions. Credit to Ben Loer of Princeton University for reporting this issue. Libsystem CVE-ID: CVE-2008-4220 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.5, Mac OS X Server v10.5 through v10.5.5 Impact: Applications that use the inet_net_pton API may be vulnerable to arbitrary code execution or an unexpected application termination Description: An integer overflow exists in Libsystem's inet_net_pton API, which may lead to arbitrary code execution or the unexpected termination of the application using the API. This update addresses the issue through improved bounds checking. This API is not normally called with untrusted data, and no exploitable cases of this issue are known. This update is provided to help mitigate potential attacks against any application using this API. Libsystem CVE-ID: CVE-2008-4221 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.5, Mac OS X Server v10.5 through v10.5.5 Impact: Applications that use the strptime API may be vulnerable to arbitrary code execution or unexpected application termination Description: A memory corruption issue exists in Libsystem's strptime API. Parsing a maliciously crafted date string may lead to arbitrary code execution or unexpected application termination. This update addresses the issue through improved memory allocation.
