Multiple integer overflows in FreeType 2.3.9 and earlier allow remote attackers to execute arbitrary code via vectors related to large values in certain inputs in (1) smooth/ftsmooth.c, (2) sfnt/ttcmap.c, and (3) cff/cffload.c.

The PNG reference library (aka libpng) before 1.0.43, and 1.2.x before 1.2.35, as used in pngcrush and other applications, allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file that triggers a free of an uninitialized pointer in (1) the png_read_png function, (2) pCAL chunk handling, or (3) setup of 16-bit gamma tables.

Safari in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 does not isolate the call-approval dialog from the process of launching new applications, which allows remote attackers to make arbitrary phone calls via a crafted HTML document.

Safari in Apple iPhone OS 2.0 through 2.1 and iPhone OS for iPod touch 2.1 through 2.1 does not restrict an IFRAME's content display to the boundaries of the IFRAME, which allows remote attackers to spoof a user interface via a crafted HTML document.

Safari in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 does not properly handle HTML TABLE elements, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document.

The Passcode Lock feature in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 displays SMS messages when the emergency-call screen is visible, which allows physically proximate attackers to obtain sensitive information by reading these messages. NOTE: this might be a duplicate of CVE-2008-4593.

Race condition in the Passcode Lock feature in Apple iPhone OS 2.0 through 2.1 and iPhone OS for iPod touch 2.0 through 2.1 allows physically proximate attackers to remove the lock and launch arbitrary applications by restoring the device from a backup.

The Passcode Lock feature in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 allows physically proximate attackers to leverage the emergency-call ability of locked devices to make a phone call to an arbitrary number.

Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 changes the encryption level of PPTP VPN connections to a lower level than was previously used, which makes it easier for remote attackers to obtain sensitive information or hijack a connection by decrypting network traffic.

ImageIO in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 allow remote attackers to cause a denial of service (memory consumption and device reset) via a crafted TIFF image.

Integer signedness error in (1) QuickLook in Apple Mac OS X 10.5.5 and (2) Office Viewer in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 allows remote attackers to cause a denial of service (application termination) and execute arbitrary code via a crafted Microsoft Excel file that triggers an out-of-bounds memory access, related to "handling of columns."

Heap-based buffer overflow in the xmlParseAttValueComplex function in parser.c in libxml2 before 2.7.0 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a long XML entity name.

libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document.

WebCore in Apple Safari does not properly perform garbage collection of JavaScript document elements, which allows remote attackers to execute arbitrary code or cause a denial of service (heap corruption and application crash) via a reference to the ownerNode property of a copied CSSStyleSheet object of a STYLE element, as originally demonstrated on Apple iPhone before 2.0 and iPod touch before 2.0, a different vulnerability than CVE-2008-1590.
