DesktopServices in Apple Mac OS X 10.6 before 10.6.3 does not properly resolve pathnames in certain circumstances involving an application's save panel, which allows user-assisted remote attackers to trigger unintended remote file copying via a crafted share name.

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."

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.

Heap-based buffer overflow in quicktime.qts in CoreMedia and QuickTime in Apple Mac OS X before 10.6.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a malformed .3g2 movie file with H.263 encoding that triggers an incorrect buffer length calculation.

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.

Buffer overflow in Image RAW in Apple Mac OS X before 10.6.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PEF image.

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.

QuickTime in Apple Mac OS X before 10.6.3 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted movie file with Sorenson encoding.

Heap-based buffer overflow in QuickTimeMPEG.qtx in QuickTime in Apple Mac OS X before 10.6.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted genl atom in a QuickTime movie file with MPEG encoding, which is not properly handled during decompression.

CoreAudio in Apple Mac OS X before 10.6.3 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via crafted audio content with QDMC encoding.
