Version(s): prior to 10.6.4
Description:   Multiple vulnerabilities were reported in Mac OS X. A remote user can cause arbitrary code to be executed on the target user's system. A local user can obtain elevated privileges on the target system. A remote user can cause denial of service conditions. A remote user can conduct cross-site scripting attacks. A remote user can view or upload files on the target system.

A remote user can create a specially crafted MPEG2 movie file that, when loaded by the target user, will trigger a memory corruption error and execute arbitrary code on the target system [CVE-2010-0543]. The code will run with the privileges of the target user. For version 10.6.x, this bug was fixed in version 10.6.2.

When "Apply to enclosed items..." is selected in the Finder "Get Info" window, the ownership of the enclosed items is not changed [CVE-2010-0545]. As a result, the enclosed files and folders may have the wrong permissions. Michi Ruepp of pianobakery.com reported this vulnerability.

A user can create a specially crafted disk image or remote share that, when unmounted by the target user, will exploit a symlink flaw in Folder Manager and cause an arbitrary folder to be deleted with the permissions of the target user [CVE-2010-0546].

A remote user can create specially crafted HTML that, when loaded by the target user, will cause arbitrary JavaScript to be executed by the Help Viewer in the local domain [CVE-2010-1373]. Systems prior to Mac OS X version 10.6 are not affected. Clint Ruoho of Laconic Security reported this vulnerability.

A remote user can exploit a directory traversal flaw in iChat to upload files to arbitrary locations on the target user's system for users that are using AIM in iChat [CVE-2010-1374].

A local user can invoke NetAuthSysAgent to execute certain operations and obtain system privileges [CVE-2010-1375]. Mac OS X version 10.6 is not affected.

A remote user can create specially crafted HTML that, when loaded by the target user, will exploit a format string flaw in the processing of 'afp:', 'cifs:', and 'smb:' URLs to execute arbitrary code on the target user's system [CVE-2010-1376]. Systems prior to Mac OS X version 10.6 are not affected. Ilja van Sprundel of IOActive and Chris Ries ofCarnegie Mellon University Computing Services reported this vulnerability.

Open Directory uses a non secure connection if an SSL connection is not available when binding to a network account server via System Preferences. A remote user with the ability to conduct a man-in-the-middle attack can impersonate a network account server [CVE-2010-1377]. Systems prior to Mac OS X version 10.6 are not affected.

A device on the local network can advertise a printing service with a Unicode character in the service name to cause printing in certain application to fail [CVE-2010-1379]. Filipp Lepalaan of mcare Oy reported this vulnerability.

A remote or local user with access to a printer can cause an integer overflow in the cgtexttops CUPS filter and execute arbitrary code [CVE-2010-1380]. Mac OS X versions prior to version 10.6 are not affected. regenrecht reported this vulnerability via iDefense.

A remote user can exploit a configuration flaw in the SMB File Server to obtain access to arbitrary files on the share [CVE-2010-1381].

A remote user can create specially crafted Wiki content that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser [CVE-2010-1382]. The code will originate from the site running the Mac OS X software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can create a specially crafted TIFF file that, when loaded by the target user, will trigger an integer overflow and execute arbitrary code on the target user's system [CVE-2010-1411]. Kevin Finisterre of digitalmunition.com reported this vulnerability.

Impact:   A remote user can create a file that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user can cause denial of service conditions.

A local user can obtain system privileges on the target system.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the target user, access data recently submitted by the target user via web form to the target site, or take actions on the target site acting as the target user.

A remote user can view files on the target system.

A remote user can upload files to arbitrary locations on the target user's system.
