Password Server in Apple Mac OS X Server before 10.6.3 does not properly perform password replication, which might allow remote authenticated users to obtain login access via an expired password.

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 QDM2 encoding, which triggers a buffer overflow due to inconsistent length fields, related to QDCA.

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.

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.
