iChat Server in Apple Mac OS X Server before 10.6.3, when group chat is used, does not perform logging for all types of messages, which might allow remote attackers to avoid message auditing via an unspecified selection of message type.

Directory traversal vulnerability in FTP Server in Apple Mac OS X Server before 10.6.3 allows remote authenticated users to read arbitrary files via crafted filenames.

Event Monitor in Apple Mac OS X before 10.6.3 does not properly validate hostnames of SSH clients, which allows remote attackers to cause a denial of service (arbitrary client blacklisting) via a crafted DNS PTR record, related to a "plist injection issue."

Directory Services in Apple Mac OS X before 10.6.3 does not properly perform authorization during processing of record names, which allows local users to gain privileges via unspecified vectors.

Disk Images in Apple Mac OS X before 10.6.3 does not provide the expected warning for an unsafe file type in an internet enabled disk image, which makes it easier for user-assisted remote attackers to execute arbitrary code via a package file type.

Disk Images in Apple Mac OS X before 10.6.3 allows user-assisted remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted disk image with bzip2 compression.

Incomplete blacklist vulnerability in CoreTypes in Apple Mac OS X before 10.6.3 makes it easier for user-assisted remote attackers to execute arbitrary JavaScript via a web page that offers a download with a Content-Type value that is not on the list of possibly unsafe content types for Safari, as demonstrated by the values for the (1) .ibplugin and (2) .url extensions.

xar in Apple Mac OS X 10.5.8 does not properly validate package signatures, which allows attackers to have an unspecified impact via a modified package.

Directory traversal vulnerability in AFP Server in Apple Mac OS X before 10.6.3 allows remote attackers to list a share root's parent directory, and read and modify files in that directory, via unspecified vectors.

freshclam in ClamAV in Apple Mac OS X 10.5.8 with Security Update 2009-005 has an incorrect launchd.plist ProgramArguments key and consequently does not run, which might allow remote attackers to introduce viruses into the system.

AFP Server in Apple Mac OS X before 10.6.3 does not prevent guest use of AFP shares when guest access is disabled, which allows remote attackers to bypass intended access restrictions via a mount request.

Buffer overflow in Cocoa spell checking in AppKit in Apple Mac OS X 10.5.8 allows user-assisted remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted document.

The Application Firewall in Apple Mac OS X 10.5.8 drops unspecified firewall rules after a reboot, which might allow remote attackers to bypass intended access restrictions via packet data, related to a "timing issue."

Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, Safari before 4.1 on Mac OS X 10.4, and Safari on Apple iPhone OS allows remote attackers to execute arbitrary code or cause a denial of service (application crash), or read the SMS database or other data, via vectors related to "attribute manipulation," as demonstrated by Vincenzo Iozzo and Ralf Philipp Weinmann during a Pwn2Own competition at CanSecWest 2010.

Buffer overflow in Image RAW in Apple Mac OS X 10.5.8 and 10.6.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted DNG image.

Buffer overflow in CoreAudio in Apple Mac OS X 10.5.8 and 10.6.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted MP4 audio file.

Java for Mac OS X 10.5 before Update 6 and 10.6 before Update 1 accepts expired certificates for applets, which makes it easier for remote attackers to execute arbitrary code via an applet.

Spotlight in Apple Mac OS X 10.5.8 does not properly handle temporary files, which allows local users to overwrite arbitrary files in the context of a different user's privileges via unspecified vectors.

Screen Sharing in Apple Mac OS X 10.5.8 allows remote VNC servers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via unspecified vectors.

The kernel in Apple Mac OS X before 10.6.2 does not properly handle task state segments, which allows local users to gain privileges, cause a denial of service (system crash), or obtain sensitive information via unspecified vectors.
