A certain Apple patch for OpenSSL in Apple OS X 10.9.2 and earlier uses a Trust Evaluation Agent (TEA) feature without terminating certain TLS/SSL handshakes as specified in the SSL_CTX_set_verify callback function's documentation, which allows remote attackers to bypass extra verification within a custom application via a crafted certificate chain that is acceptable to TEA but not acceptable to that application.

Buffer overflow in the socket.recvfrom_into function in Modules/socketmodule.c in Python 2.5 before 2.7.7, 3.x before 3.3.4, and 3.4.x before 3.4rc1 allows remote attackers to execute arbitrary code via a crafted string.

The systemsetup program in the Date and Time subsystem in Apple OS X before 10.9.2 allows local users to bypass intended access restrictions by changing the current time on the system clock.

Finder in Apple OS X before 10.9.2 does not ensure ACL integrity after the viewing of file ACL information, which allows local users to bypass intended access restrictions in opportunistic circumstances via standard filesystem operations on a file with a damaged ACL.

curl and libcurl 7.27.0 through 7.35.0, when using the SecureTransport/Darwinssl backend, as used in in Apple OS X 10.9.x before 10.9.2, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate when accessing a URL that uses a numerical IP address, which allows man-in-the-middle attackers to spoof servers via an arbitrary valid certificate.

Apple Type Services (ATS) in Apple OS X before 10.9.2 allows attackers to bypass the App Sandbox protection mechanism via crafted Mach messages that trigger memory corruption.

Integer signedness error in CoreText in Apple OS X before 10.9.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted Unicode font.

QuickLook in Apple OS X through 10.8.5 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted Microsoft Office document.

Buffer overflow in File Bookmark in Apple OS X before 10.9.2 allows attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted filename.

Heap-based buffer overflow in CoreAnimation in Apple OS X before 10.9.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted image.

CFNetwork in Apple OS X through 10.8.5 does not remove session cookies upon a Safari reset action, which allows physically proximate attackers to bypass intended access restrictions by leveraging an unattended workstation.

Buffer overflow in Apple Type Services (ATS) in Apple OS X before 10.9.2 allows attackers to bypass the App Sandbox protection mechanism via crafted Mach messages.

Apple Type Services (ATS) in Apple OS X before 10.9.2 does not properly validate calls to the free function, which allows attackers to bypass the App Sandbox protection mechanism via crafted Mach messages.

Apple Type Services (ATS) in Apple OS X before 10.9.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted Type 1 font that is embedded in a document.

Double free vulnerability in Apple Pages 2.x before 2.1 and 5.x before 5.1 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted Microsoft Word file.

The asn1_time_to_time_t function in ext/openssl/openssl.c in PHP before 5.3.28, 5.4.x before 5.4.23, and 5.5.x before 5.5.7 does not properly parse (1) notBefore and (2) notAfter timestamps in X.509 certificates, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted certificate that is not properly handled by the openssl_x509_parse function.

The scan function in ext/date/lib/parse_iso_intervals.c in PHP through 5.5.6 does not properly restrict creation of DateInterval objects, which might allow remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted interval specification.

The USB hub controller in Apple Mac OS X before 10.9 allows local users to cause a denial of service (system crash) via a request with a crafted (1) port or (2) port number.

The syslog implementation in Apple Mac OS X before 10.9 allows local users to obtain sensitive information by leveraging access to the Guest account and reading console-log messages from previous Guest sessions.

Smart Card Services in Apple Mac OS X before 10.9 does not properly implement certificate-revocation checks, which allows remote attackers to cause a denial of service (Smart Card usage outage) by interfering with the revocation-check procedure.
