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.

Apple Filing Protocol (AFP) Server in Apple Mac OS X 10.6.x through 10.6.4 does not properly handle errors, which allows remote attackers to bypass the password requirement for shared-folder access by leveraging knowledge of a valid account name.

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.

CFNetwork in Apple Mac OS X 10.6.3 and 10.6.4 supports anonymous SSL and TLS connections, which allows man-in-the-middle attackers to redirect a connection and obtain sensitive information via crafted responses.

ImageIO in Apple Mac OS X 10.5.8, and 10.6 before 10.6.2, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted movie file with MPEG2 encoding.

Cross-site scripting (XSS) vulnerability in Help Viewer in Apple Mac OS X 10.6 before 10.6.4 allows remote attackers to inject arbitrary web script or HTML via a crafted help: URL, related to "URL parameters in HTML content."

Cross-site scripting (XSS) vulnerability in Wiki Server in Apple Mac OS X 10.5.8, and 10.6 before 10.6.4, allows remote authenticated users to inject arbitrary web script or HTML via crafted Wiki content, related to lack of a charset field.

Open Directory in Apple Mac OS X 10.6 before 10.6.4 creates an unencrypted connection upon certain SSL failures, which allows man-in-the-middle attackers to spoof arbitrary network account servers, and possibly execute arbitrary code, via unspecified vectors.
