The Certificate Trust Policy component in Apple Mac OS X before 10.6.8 does not perform CRL checking for Extended Validation (EV) certificates that lack OCSP URLs, which might allow man-in-the-middle attackers to spoof an SSL server via a revoked certificate.

Heap-based buffer overflow in Apple Type Services (ATS) in Apple Mac OS X before 10.6.8 allows remote attackers to execute arbitrary code via a crafted embedded TrueType font.

App Store in Apple Mac OS X before 10.6.8 creates a log entry containing a user's AppleID password, which might allow local users to obtain sensitive information by reading a log file, as demonstrated by a log file that has non-default permissions.

AirPort in Apple Mac OS X 10.5.8 allows remote attackers to cause a denial of service (out-of-bounds read and reboot) via Wi-Fi frames on the local wireless network.

The generate-id XPath function in libxslt in Apple iOS 4.3.x before 4.3.2 allows remote attackers to obtain potentially sensitive information about heap memory addresses via a crafted web site. NOTE: this may overlap CVE-2011-1202.

Integer overflow in ImageIO in Apple Mac OS X 10.6 before 10.6.7 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted TIFF image with JPEG encoding.

Multiple buffer overflows in Image RAW in Apple Mac OS X before 10.6.7 allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted Canon RAW image.

Buffer overflow in Fax4Decode in LibTIFF 3.9.4 and possibly other versions, as used in ImageIO in Apple iTunes before 10.2 on Windows and other products, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted TIFF Internet Fax image file that has been compressed using CCITT Group 4 encoding, related to the EXPAND2D macro in libtiff/tif_fax3.h. NOTE: some of these details are obtained from third party information.

Buffer overflow in LibTIFF 3.9.4 and possibly other versions, as used in ImageIO in Apple iTunes before 10.2 on Windows and other products, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted TIFF image with JPEG encoding.

Install Helper in Installer in Apple Mac OS X before 10.6.7 does not properly process an unspecified URL, which might allow remote attackers to track user logins by logging network traffic from an agent that was intended to send network traffic to an Apple server.

The default configuration of Terminal in Apple Mac OS X 10.6 before 10.6.7 uses SSH protocol version 1 within the New Remote Connection dialog, which might make it easier for man-in-the-middle attackers to spoof SSH servers by leveraging protocol vulnerabilities.

The VpMemAlloc function in bigdecimal.c in the BigDecimal class in Ruby 1.9.2-p136 and earlier, as used on Apple Mac OS X before 10.6.7 and other platforms, does not properly allocate memory, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving creation of a large BigDecimal value within a 64-bit process, related to an "integer truncation issue."

The plug-in in QuickTime in Apple Mac OS X before 10.6.7 allows remote attackers to bypass the Same Origin Policy and obtain potentially sensitive video data via vectors involving a cross-site redirect.

QuickTime in Apple Mac OS X before 10.6.7 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted JPEG2000 image.

Format string vulnerability in the debug-logging feature in Application Firewall in Apple Mac OS X before 10.7.2 allows local users to gain privileges via a crafted name of an executable file.

QuickLook in Apple Mac OS X 10.6 before 10.6.7 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via an Excel spreadsheet with a crafted formula that uses unspecified opcodes.

Libinfo in Apple Mac OS X before 10.6.7 does not properly handle an unspecified integer field in an NFS RPC packet, which allows remote attackers to cause a denial of service (lockd, statd, mountd, or portmap outage) via a crafted packet, related to an "integer truncation issue."

The i386_set_ldt system call in the kernel in Apple Mac OS X before 10.6.7 does not properly handle call gates, which allows local users to gain privileges via vectors involving the creation of a call gate entry.

Integer overflow in ImageIO in Apple Mac OS X before 10.6.7 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted XBM image.

Integer overflow in HFS in Apple Mac OS X before 10.6.7 allows local users to read arbitrary (1) HFS, (2) HFS+, or (3) HFS+J files via a crafted F_READBOOTSTRAP ioctl call.
