Samba 3.4 before 3.4.2, 3.3 before 3.3.8, 3.2 before 3.2.15, and 3.0.12 through 3.0.36, as used in the SMB subsystem in Apple Mac OS X 10.5.8 when Windows File Sharing is enabled, Fedora 11, and other operating systems, does not properly handle errors in resolving pathnames, which allows remote authenticated users to bypass intended sharing restrictions, and read, create, or modify files, in certain circumstances involving user accounts that lack home directories.

XNU 1228.9.59 and earlier on Apple Mac OS X 10.5.6 and earlier does not properly restrict interaction between user space and the HFS IOCTL handler, which allows local users to overwrite kernel memory and gain privileges by attaching an HFS+ disk image and performing certain steps involving HFS_GET_BOOT_INFO fcntl calls.

CFNetwork in Apple Safari before 4.0 on Windows does not properly protect the temporary files created for downloads, which allows local users to obtain sensitive information by reading these files.

The Profiles component in Apple iPhone OS 1.0 through 2.2.1 and iPhone OS for iPod touch 1.1 through 2.2.1, when installing a configuration profile, can replace the password policy from Exchange ActiveSync with a weaker password policy, which allows physically proximate attackers to bypass the intended policy.

Apple Safari executes DOM calls in response to a javascript: URI in the target attribute of a submit element within a form contained in an inline PDF file, which might allow remote attackers to bypass intended Adobe Acrobat JavaScript restrictions on accessing the document object, as demonstrated by a web site that permits PDF uploads by untrusted users, and therefore has a shared document.domain between the web site and this javascript: URI. NOTE: the researcher reports that Adobe's position is "a PDF file is active content."

Weblog in Mac OS X Server 10.4.11 does not properly check an error condition when a weblog posting access control list is specified for a user that has multiple short names, which might allow attackers to bypass intended access restrictions.

Incomplete blacklist vulnerability in the Quarantine feature in CoreTypes in Apple Mac OS X 10.5 before 10.5.6 allows user-assisted remote attackers to execute arbitrary code via an executable file with the content type indicating no application association for the file, which does not trigger a "potentially unsafe" warning message.

Certificate Assistant in Apple Mac OS X 10.5.6 allows local users to overwrite arbitrary files via unknown vectors related to an "insecure file operation" on a temporary file.

The kernel in Apple Mac OS X 10.5 through 10.5.4 does not properly flush cached credentials during recycling (aka purging) of a vnode, which might allow local users to bypass the intended read or write permissions of a file.

Application Sandbox in Apple iPod touch 2.0 through 2.0.2, and iPhone 2.0 through 2.0.2, does not properly isolate third-party applications, which allows attackers to read arbitrary files in a third-party application's sandbox via a different third-party application.

Apple iPhone 2.0.2, in some configurations, allows physically proximate attackers to bypass intended access restrictions, and obtain sensitive information or make arbitrary use of the device, via an Emergency Call tap and a Home double-tap, followed by a tap of any contact's blue arrow.

Apple Safari allows web sites to set cookies for country-specific top-level domains, such as co.uk and com.au, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session, aka "Cross-Site Cooking," a related issue to CVE-2004-0746, CVE-2004-0866, and CVE-2004-0867.

The File Sharing pane in the Sharing preference pane in Apple Mac OS X 10.5 through 10.5.4 does not inform users that the complete contents of their own home directories are shared for their own use, which might allow attackers to leverage other vulnerabilities and access files for which sharing was unintended.

Incomplete blacklist vulnerability in CoreTypes in Apple Mac OS X before 10.5.4 allows user-assisted remote attackers to execute arbitrary code via a (1) .xht or (2) .xhtm file, which does not trigger a "potentially unsafe" warning message in (a) the Download Validation feature in Mac OS X 10.4 or (b) the Quarantine feature in Mac OS X 10.5.

Open Scripting Architecture in Apple Mac OS X 10.4.11 and 10.5.4, and some other 10.4 and 10.5 versions, does not properly restrict the loading of scripting addition plugins, which allows local users to gain privileges via scripting addition commands to a privileged application, as originally demonstrated by an osascript tell command to ARDAgent.

Finder in Apple Mac OS X 10.5 through 10.5.4 does not properly update permission data in the Get Info window after a lock operation that modifies Sharing & Permissions in a filesystem, which might allow local users to leverage weak permissions that were not intended by an administrator.

Apple Safari on Mac OS X, and before 3.1.2 on Windows, does not prompt the user before downloading an object that has an unrecognized content type, which allows remote attackers to place malware into the (1) Desktop directory on Windows or (2) Downloads directory on Mac OS X, and subsequently allows remote attackers to execute arbitrary code on Windows by leveraging an untrusted search path vulnerability in (a) Internet Explorer 7 on Windows XP or (b) the SearchPath function in Windows XP, Vista, and Server 2003 and 2008, aka a "Carpet Bomb" and a "Blended Threat Elevation of Privilege Vulnerability," a different issue than CVE-2008-1032. NOTE: Apple considers this a vulnerability only because the Microsoft products can load application libraries from the desktop and, as of 20080619, has not covered the issue in an advisory for Mac OS X.

The Application Firewall in Apple Mac OS X 10.5.2 has an incorrect German translation for the "Set access for specific services and applications" radio button that might cause the user to believe that the button is used to restrict access only to specific services and applications, which might allow attackers to bypass intended access restrictions.

iChat in Apple Mac OS X 10.4.11 allows network-adjacent remote attackers to automatically initiate a video connection to another user via unknown vectors.
