libsecurity in Apple Mac OS X before 10.7.4 does not properly restrict the length of RSA keys within X.509 certificates, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by conducting a spoofing or network-sniffing attack during communication with a site that uses a short key.

libsecurity in Apple Mac OS X before 10.7.4 accesses uninitialized memory locations during the processing of X.509 certificates, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted certificate.

Integer overflow in libpng, as used in Google Chrome before 17.0.963.56, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that trigger an integer truncation.

Heap-based buffer overflow in CoreMedia in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted movie file with H.264 encoding.

Off-by-one error in QuickTime in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted rdrf atom in a movie file that triggers a buffer overflow.

Buffer overflow in QuickTime in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PNG file.

The OpenGL implementation in Apple Mac OS X before 10.7.3 does not properly perform OpenGL Shading Language (aka GLSL) compilation, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted program.

Apple Type Services (ATS) in Apple Mac OS X through 10.6.8 does not properly handle embedded Type 1 fonts, which allows remote attackers to execute arbitrary code via a crafted document that triggers an out-of-bounds memory access.

MediaKit in Apple Mac OS X through 10.6.8 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted disk image.

QuickTime in Apple Mac OS X before 10.7.2 does not properly handle the atom hierarchy in movie files, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted file.
