Heap-based buffer overflow in the xmlParseAttValueComplex function in parser.c in libxml2 before 2.7.0 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a long XML entity name.

libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document.

Stack-based buffer overflow in Apple QuickTime before 7.3.1, as used in QuickTime Player on Windows XP and Safari on Mac OS X, allows remote Real Time Streaming Protocol (RTSP) servers to execute arbitrary code via an RTSP response with a long Content-Type header.

Format string vulnerability in iMovie HD 6.0.3, and Safari in Apple Mac OS X 10.4 through 10.4.10, allows remote user-assisted attackers to cause a denial of service (crash) via format string specifiers in a filename, which is not properly handled when calling the NSRunCriticalAlertPanel Apple AppKit function.
