Apple Mac OS X before 10.5 uses weak permissions for the User Template directory, which allows local users to gain privileges by inserting a Trojan horse file into this directory.

Dock in Apple Mac OS X 10.5 before 10.5.4, when Exposé hot corners is enabled, allows physically proximate attackers to gain access to a locked session in (1) sleep mode or (2) screen saver mode via unspecified vectors.

Incomplete blacklist vulnerability in CoreTypes in Apple Mac OS X before 10.5.4 allows user-assisted remote attackers to execute arbitrary code via a (1) .xht or (2) .xhtm file, which does not trigger a "potentially unsafe" warning message in (a) the Download Validation feature in Mac OS X 10.4 or (b) the Quarantine feature in Mac OS X 10.5.

Launch Services in Apple Mac OS X before 10.5, when Open Safe Files is enabled, allows remote attackers to execute arbitrary code via a symlink attack, probably related to a race condition and automatic execution of a downloaded file.

Format string vulnerability in c++filt in Apple Mac OS X 10.5 before 10.5.4 allows user-assisted attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted string in (1) C++ or (2) Java source code.

Unspecified vulnerability in Alias Manager in Apple Mac OS X 10.5.1 and earlier on Intel platforms allows local users to gain privileges or cause a denial of service (memory corruption and application crash) by resolving an alias that contains crafted AFP volume mount information.

Integer overflow in the CFDataReplaceBytes function in the CFData API in CoreFoundation in Apple Mac OS X before 10.5.3 allows context-dependent attackers to execute arbitrary code or cause a denial of service (crash) via an invalid length argument, which triggers a heap-based buffer overflow.

Wiki Server in Apple Mac OS X 10.5 before 10.5.3 allows remote attackers to obtain sensitive information (user names) by reading the error message produced upon access to a nonexistent blog.

Integer overflow in ImageIO in Apple Mac OS X before 10.5.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted JPEG2000 image that triggers a heap-based buffer overflow.

The International Components for Unicode (ICU) library in Apple Mac OS X before 10.5.3, Red Hat Enterprise Linux 5, and other operating systems omits some invalid character sequences during conversion of some character encodings, which might allow remote attackers to conduct cross-site scripting (XSS) attacks.
