The plug-in interface in WebKit in Apple Safari before 3.2 does not prevent plug-ins from accessing local URLs, which allows remote attackers to obtain sensitive information via vectors that "launch local files."

Unspecified vulnerability in WebKit in Apple Safari before 3.1.2, as distributed in Mac OS X before 10.5.4, and standalone for Windows and Mac OS X 10.4, allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via vectors involving JavaScript arrays that trigger memory corruption.

Apple Safari before 3.1.2 on Windows does not properly interpret the URLACTION_SHELL_EXECUTE_HIGHRISK Internet Explorer zone setting, which allows remote attackers to bypass intended access restrictions, and force a client system to download and execute arbitrary files.

Apple Safari 3.1.1 allows remote attackers to cause a denial of service (application crash) via a file:///%E2 link that triggers an out-of-bounds access, possibly due to a NULL pointer dereference.

Apple Safari 3.1.1 allows remote attackers to spoof the address bar by placing many "invisible" characters in the userinfo subcomponent of the authority component of the URL (aka the user field), as demonstrated by %E3%80%80 sequences.

Unspecified vulnerability in Apple Safari 3.1.1 allows remote attackers to cause a denial of service (application crash) via JavaScript code that calls document.write in an infinite loop.

Integer overflow in the PCRE regular expression compiler (JavaScriptCore/pcre/pcre_compile.cpp) in Apple WebKit, as used in Safari before 3.1.1, allows remote attackers to execute arbitrary code via a regular expression with large, nested repetition counts, which triggers a heap-based buffer overflow.

Cross-site scripting (XSS) vulnerability in Apple WebKit, as used in Safari before 3.1.1, allows remote attackers to inject arbitrary web script or HTML via a crafted URL with a colon in the hostname portion.

Apple Safari before 3.1.1, when running on Windows XP or Vista, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a file download with a crafted file name, which triggers memory corruption.
