Mail in Apple Mac OS X before 10.6.3 does not properly enforce the key usage extension during processing of a keychain that specifies multiple certificates for an e-mail recipient, which might make it easier for remote attackers to obtain sensitive information via a brute-force attack on a weakly encrypted e-mail message.

Stack-based buffer overflow in PS Normalizer 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 PostScript document.

SFLServer in OS Services in Apple Mac OS X before 10.6.3 allows local users to gain privileges via vectors related to use of wheel group membership during access to the home directories of user accounts.

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.

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.

Heap-based buffer overflow in ImageIO 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 JP2 (JPEG2000) image, related to incorrect calculation and the CGImageReadGetBytesAtOffset function.

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.

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.

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.

Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS before 1.4.4, when kqueue or epoll is used, allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third party information. NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-3553.

The png_decompress_chunk function in pngrutil.c in libpng 1.0.x before 1.0.53, 1.2.x before 1.2.43, and 1.4.x before 1.4.1 does not properly handle compressed ancillary-chunk data that has a disproportionately large uncompressed representation, which allows remote attackers to cause a denial of service (memory and CPU consumption, and application hang) via a crafted PNG file, as demonstrated by use of the deflate compression method on data composed of many occurrences of the same character, related to a "decompression bomb" attack.

Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS 1.3.7 and 1.3.10 allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third party information.

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.

IOKit in Apple Mac OS X before 10.6.2 allows local users to modify the firmware of a (1) USB or (2) Bluetooth keyboard via unspecified vectors.

Certificate Assistant in Apple Mac OS X before 10.6.2 does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

The Apache HTTP Server in Apple Mac OS X before 10.6.2 enables the HTTP TRACE method, which allows remote attackers to conduct cross-site scripting (XSS) attacks via unspecified web client software.
