AFP Server in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon restart) via crafted reconnect authentication packets.

Buffer overflow in Apple Type Services (ATS) in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code via a long name of an embedded font in a document.

Directory Services in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 does not properly handle errors associated with disabled mobile accounts, which allows remote attackers to bypass authentication by providing a valid account name.

CoreText in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted font in a PDF document.

Disk Images in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted UDIF image.

Stack-based buffer overflow in the password-validation functionality in Directory Services in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors.

Stack-based buffer overflow in CoreGraphics in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PDF document.

Heap-based buffer overflow in CoreGraphics in Apple Mac OS X 10.5.8 and 10.6.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PDF file.

libsecurity in Apple Mac OS X 10.5.8 and 10.6.4 does not properly perform comparisons to domain-name strings in X.509 certificates, which allows man-in-the-middle attackers to spoof SSL servers via a certificate associated with a similar domain name, as demonstrated by use of a www.example.con certificate to spoof www.example.com.

Stack-based buffer overflow in Apple Type Services (ATS) in Apple Mac OS X 10.5.8 and 10.6.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted embedded font in a document.
