The File Systems component in Apple Mac OS X before 10.7.2 does not properly track the specific X.509 certificate that a user manually accepted for an initial https WebDAV connection, which allows man-in-the-middle attackers to hijack WebDAV communication by presenting an arbitrary certificate for a subsequent connection.

Buffer overflow in QuickTime in Apple Mac OS X before 10.7.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted FlashPix file.

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.

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.

Use-after-free vulnerability in iChat Server in Apple Mac OS X Server 10.5.8 allows remote authenticated users to execute arbitrary code or cause a denial of service (application crash) 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.

Mail in Apple Mac OS X before 10.6.3 does not disable the filter rules associated with a deleted mail account, which has unspecified impact and attack vectors.

Server Admin in Apple Mac OS X Server before 10.6.3 does not properly enforce authentication for directory binding, which allows remote attackers to obtain potentially sensitive information from Open Directory via unspecified LDAP requests.

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.
