Integer overflow in the Security Framework in Apple Mac OS X before 10.7.4 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via crafted input.
Time Machine in Apple Mac OS X before 10.7.4 does not require continued use of SRP-based authentication after this authentication method is first used, which allows remote attackers to read Time Capsule credentials by spoofing the backup volume.
Race condition in the initialization routine in blued in Bluetooth in Apple Mac OS X before 10.7.4 allows local users to gain privileges via vectors involving a temporary file.
The directory server in Directory Service in Apple Mac OS X 10.6.8 allows remote attackers to obtain sensitive information from process memory via a crafted message.
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.
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.
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.
Address Book in Apple Mac OS X before 10.7.3 automatically switches to unencrypted sessions upon failure of encrypted connections, which allows remote attackers to read CardDAV data by terminating an encrypted connection and then sniffing the network.
Apple Type Services (ATS) in Apple Mac OS X before 10.7.3 does not properly manage memory for data-font files, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted font that is accessed by Font Book.
CFNetwork in Apple Mac OS X 10.7.x before 10.7.3 does not properly construct request headers during parsing of URLs, which allows remote attackers to obtain sensitive information via a malformed URL.
