Memory leak in pngrutil.c in libpng before 1.2.44, and 1.4.x before 1.4.3, allows remote attackers to cause a denial of service (memory consumption and application crash) via a PNG image containing malformed Physical Scale (aka sCAL) chunks.

Buffer overflow in pngpread.c in libpng before 1.2.44 and 1.4.x before 1.4.3, as used in progressive applications, might allow remote attackers to execute arbitrary code via a PNG image that triggers an additional data row.

Race condition in Passcode Lock in Apple iOS before 4 on the iPhone and iPod touch allows physically proximate attackers to bypass intended passcode requirements, and pair a locked device with a computer and access arbitrary data, via vectors involving the initial boot.

WebKit in Apple iOS before 4 on the iPhone and iPod touch does not enforce the expected boundary restrictions on content display by an IFRAME element, which allows remote attackers to spoof the user interface via a crafted HTML document.

The Settings application in Apple iOS before 4 on the iPhone and iPod touch does not properly report the wireless network that is in use, which might make it easier for remote attackers to trick users into communicating over an unintended network.

Safari in Apple iOS before 4 on the iPhone and iPod touch does not properly implement the Accept Cookies preference, which makes it easier for remote web servers to track users via a cookie.

Passcode Lock in Apple iOS before 4 on the iPhone and iPod touch does not properly handle alert-based unlocks in conjunction with subsequent Remote Lock operations through MobileMe, which allows physically proximate attackers to bypass intended passcode requirements via unspecified vectors.

ImageIO in Apple iOS before 4 on the iPhone and iPod touch allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted JPEG image.

Stack-based buffer overflow in CFNetwork in Apple iOS before 4 on the iPhone and iPod touch allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to URL handling.

Application Sandbox in Apple iOS before 4 on the iPhone and iPod touch does not prevent photo-library access, which might allow remote attackers to obtain location information via unspecified vectors.

WebKit in Apple iOS before 4 on the iPhone and iPod touch does not properly implement the history.replaceState method in certain situations involving IFRAME elements, which allows remote attackers to obtain sensitive information via a crafted HTML document.

Use-after-free vulnerability in JavaScriptCore in WebKit in Apple iTunes before 9.2 on Windows, and Apple iOS before 4 on the iPhone and iPod touch, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to page transitions, a different vulnerability than CVE-2010-1763 and CVE-2010-1769.

Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, Safari before 4.1 on Mac OS X 10.4, and Safari on Apple iPhone OS allows remote attackers to execute arbitrary code or cause a denial of service (application crash), or read the SMS database or other data, via vectors related to "attribute manipulation," as demonstrated by Vincenzo Iozzo and Ralf Philipp Weinmann during a Pwn2Own competition at CanSecWest 2010.

Stack consumption vulnerability in the WebCore::CSSSelector function in WebKit, as used in Apple Safari 4.0.4, Apple Safari on iPhone OS and iPhone OS for iPod touch, and Google Chrome 4.0.249, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a STYLE element composed of a large number of *> sequences.

Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via an HTML document with improperly nested tags.

FreeBit ServersMan 3.1.5 on Apple iPhone OS 3.1.2, and iPhone OS for iPod touch, allows remote attackers to cause a denial of service (daemon crash) via a HEAD request for the / URI.

Recovery Mode in Apple iPhone OS 1.0 through 3.1.2, and iPhone OS for iPod touch 1.1 through 3.1.2, allows physically proximate attackers to bypass device locking, and read or modify arbitrary data, via a USB control message that triggers memory corruption.

The implementation of Cross-Origin Resource Sharing (CORS) in WebKit, as used in Apple Safari before 4.0.4 and Google Chrome before 3.0.195.33, includes certain custom HTTP headers in the OPTIONS request during cross-origin operations with preflight, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via a crafted web page.

Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework.
