Description:
Apple has issued a security update for Mac OS X, which fixes multiple vulnerabilities.
1) An infinite loop when processing certain embedded fonts in PDF files within the Apple Type Services server can be exploited to cause a DoS (Denial of Service) by e.g. tricking a user into opening a malicious PDF file.
2) A signedness error when handling certain CPIO archive headers exists within BOM. This can be exploited to execute arbitrary code by e.g. downloading or viewing a specially crafted CPIO archive.
3) An error within the processing of color spaces within CoreGraphics can be exploited to cause a heap-based buffer overflow by e.g. tricking a user into viewing a specially crafted image.
Successful exploitation may allow the execution of arbitrary code.
4) Some security issues and vulnerabilities have been reported in Adobe Flash Player, which can be exploited by malicious people to bypass certain security restrictions, manipulate certain data, conduct cross-site scripting attacks, or disclose sensitive information.
For more information:
SA32270
5) Multiple integer overflows exist within the "i386_set_ldt()" and "i386_get_ldt()" system calls, which can be exploited by malicious, local users to execute arbitrary code with system privileges.
Note: This does not affect PowerPC systems.
6) An infinite loop when handling exceptions in an application linked to libraries on an NFS share can be exploited to cause a system shutdown.
7) An integer overflow error exists in the "inet_net_pton()" API of Libsystem. This can potentially be exploited to e.g. compromise an application using the vulnerable function.
8) An unspecified error when processing certain input within the "strptime()" API of Libsystem can be exploited to cause a memory corruption and potentially execute arbitrary code by e.g. passing a specially crafted date string to an application using the vulnerable function.
9) The "Managed Client" functionality does not always apply the managed screen saver settings correctly, potentially resulting in e.g. the screen saver lock not working as intended.
10) An infinite loop when processing certain TCP packets exists in natd, which can be exploited to cause a DoS by sending specially crafted TCP packets to a vulnerable system.
Successful exploitation requires that Internet Sharing is enabled.
11) An unspecified error within the Podcast Producer server can be exploited to bypass the authentication mechanism and access administrative functions.
12) An unspecified error within the handling of malformed UDF volumes can be exploited to cause a system shutdown by e.g. opening a specially crafted ISO file.
Additionally, this update enhances the CoreTypes "Download Validation" capability to detect and warn about more potentially dangerous file types.
