ImageIO in Apple iOS before 4.1 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 TIFF file.

FaceTime in Apple iOS before 4.1 on the iPhone and iPod touch does not properly handle invalid X.509 certificates, which allows man-in-the-middle attackers to redirect calls via a crafted certificate.

The Accessibility component in Apple iOS before 4.1 on the iPhone and iPod touch does not perform the expected VoiceOver announcement associated with the location services icon, which has unspecified impact and attack vectors.

Double free vulnerability in WebKit in Apple iOS before 4.1 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 the rendering of an inline element.

WebKit, as used in Apple Safari before 4.1.3 and 5.0.x before 5.0.3, Google Chrome before 6.0.472.53, and webkitgtk before 1.2.6, does not properly restrict read access to images derived from CANVAS elements, which allows remote attackers to bypass the Same Origin Policy and obtain potentially sensitive image data via a crafted web site.

Use-after-free vulnerability in WebKit, as used in Apple Safari before 4.1.3 and 5.0.x before 5.0.3, Google Chrome before 6.0.472.53, and webkitgtk before 1.2.6, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving element focus.

Multiple use-after-free vulnerabilities in WebKit, as used in Apple Safari before 4.1.3 and 5.0.x before 5.0.3, Google Chrome before 5.0.375.127, and webkitgtk before 1.2.6, allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to improper handling of MIME types by plug-ins.

Buffer overflow in the Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted Adobe Type 1 Mac Font File (aka LWFN) font.

FreeType before 2.4.2 uses incorrect integer data types during bounds checking, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file.

Array index error in the t42_parse_sfnts function in type42/t42parse.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via negative size values for certain strings in FontType42 font files, leading to a heap-based buffer overflow.

The FT_Stream_EnterFrame function in base/ftstream.c in FreeType before 2.4.2 does not properly validate certain position values, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file.

Multiple stack-based buffer overflows in the cff_decoder_parse_charstrings function in the CFF Type2 CharStrings interpreter in cff/cffgload.c in FreeType before 2.4.2, as used in Apple iOS before 4.0.2 on the iPhone and iPod touch and before 3.2.2 on the iPad, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted CFF opcodes in embedded fonts in a PDF document, as demonstrated by JailbreakMe. NOTE: some of these details are obtained from third party information.

Integer overflow in IOSurface in Apple iOS before 4.0.2 on the iPhone and iPod touch, and before 3.2.2 on the iPad, allows local users to gain privileges via vectors involving IOSurface properties, as demonstrated by JailbreakMe.
