Apple iPhone OS 6.1.3

kextd in Kext Management in Apple iOS before 7 does not properly verify authorization for IPC messages, which allows local users to (1) load or (2) unload kernel extensions via a crafted message.

The get_xattrinfo function in the XNU kernel in Apple iOS 5.x and 6.x through 6.1.3 on iPad devices does not properly validate the header of an AppleDouble file, which might allow local users to cause a denial of service (memory corruption) or have unspecified other impact via an invalid file on an msdosfs filesystem.

The IPv6 implementation in the kernel in Apple iOS before 7 allows remote attackers to cause a denial of service (CPU consumption) via crafted ICMPv6 packets.

Data Protection in Apple iOS before 7 allows attackers to bypass intended limits on incorrect passcode entry, and consequently avoid a configured Erase Data setting, by leveraging the presence of an app in the third-party sandbox.

The IPSec implementation in Apple Mac OS X before 10.8.5, when Hybrid Auth is used, does not verify X.509 certificates from security gateways, which allows man-in-the-middle attackers to spoof security gateways and obtain sensitive information via a crafted certificate.

libxml2 before 2.8.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data.

Stack-based buffer overflow in the openSharedCacheFile function in dyld.cpp in dyld in Apple iOS 5.1.x and 6.x through 6.1.3 makes it easier for attackers to conduct untethering attacks via a long string in the DYLD_SHARED_CACHE_DIR environment variable.

The Twitter subsystem in Apple iOS before 7 does not require API conformity for access to Twitter daemon interfaces, which allows attackers to post Tweets via a crafted app that sends direct requests to the daemon.

The mach_port_space_info function in osfmk/ipc/mach_debug.c in the XNU kernel in Apple Mac OS X 10.8.x does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory via a crafted call.

The kernel in Apple iOS before 7 does not initialize unspecified kernel data structures, which allows local users to obtain sensitive information from kernel stack memory via the (1) msgctl API or (2) segctl API.

IOCatalogue in IOKitUser in Apple iOS before 7 allows attackers to cause a denial of service (NULL pointer dereference and device crash) via a crafted application.

sys/openbsd/stack_protector.c in libc in Apple iOS 6.1.3 and Mac OS X 10.8.x does not properly parse the Apple strings employed in the user-space stack-cookie implementation, which allows local users to bypass cookie randomization by executing a program with a call-path beginning with the stack-guard= substring, as demonstrated by an iOS untethering attack or an attack against a setuid Mac OS X program.

libxslt 1.1.26 and earlier, as used in Google Chrome before 21.0.1180.89, does not properly manage memory, which might allow remote attackers to cause a denial of service (application crash) via a crafted XSLT expression that is not properly identified during XPath navigation, related to (1) the xsltCompileLocationPathPattern function in libxslt/pattern.c and (2) the xsltGenerateIdFunction function in libxslt/functions.c.

WebKit in Apple iOS before 7 allows remote attackers to bypass the Same Origin Policy and obtain potentially sensitive information about use of the window.webkitRequestAnimationFrame API via an IFRAME element.

Apple iOS 6.1.3 does not follow redirects during determination of the hostname to display in an iOS Enterprise Deployment installation dialog, which makes it easier for remote attackers to trigger installation of arbitrary applications via a download-manifest itms-services:// URL that leverages an open redirect vulnerability within a trusted domain.

Mobile Safari in Apple iOS before 7 does not prevent HTML interpretation of a document served with a text/plain content type, which allows remote attackers to conduct cross-site scripting (XSS) attacks by uploading a file.

Multiple cross-site scripting (XSS) vulnerabilities in WebKit in Apple iOS before 7 allow user-assisted remote attackers to inject arbitrary web script or HTML via vectors involving a (1) drag-and-drop or (2) copy-and-paste operation.

Cross-site scripting (XSS) vulnerability in WebKit in Apple iOS before 7 allows remote attackers to inject arbitrary web script or HTML via a crafted URL.

Mobile Safari in Apple iOS before 7 allows remote attackers to spoof the URL bar via a crafted web site.

The Sandbox subsystem in Apple iOS before 7 determines the sandboxing requirement for a #! application on the basis of the script interpreter instead of the script, which allows attackers to bypass intended access restrictions via a crafted application.

The Telephony subsystem in Apple iOS before 7 does not require API conformity for access to telephony-daemon interfaces, which allows attackers to bypass intended restrictions on phone calls via a crafted app that sends direct requests to the daemon.

The Push Notifications subsystem in Apple iOS before 7 provides the push-notification token to an app without user approval, which allows attackers to obtain sensitive information via an app that employs a crafted push-notification registration process.

Passcode Lock in Apple iOS before 7 does not properly manage the lock state, which allows physically proximate attackers to bypass an intended passcode requirement by leveraging a race condition involving phone calls and ejection of a SIM card.

IOKit in Apple iOS before 7 allows attackers to send user-interface events to the foreground app by leveraging control over a background app and using the (1) task-completion API or (2) VoIP API.

Springboard in Apple iOS before 7 does not properly manage the lock state in Lost Mode, which allows physically proximate attackers to read notifications via unspecified vectors.

The Social subsystem in Apple iOS before 7 does not properly restrict access to the cache of Twitter icons, which allows physically proximate attackers to obtain sensitive information about recent Twitter interaction via unspecified vectors.

The history-clearing feature in Safari in Apple iOS before 7 does not clear the back/forward history of an open tab, which allows physically proximate attackers to obtain sensitive information by leveraging an unattended workstation.
