Vulnerability Note VU#475645

Macromedia Flash plug-in contains buffer overflow

Original Release date: 17 May 2001 | Last revised: 20 Jun 2001


Incorrectly formatted sound wave (SWF) files may cause a buffer overflow in the Macromedia Flash plug-in.


If the length fields in an SWF file specify fewer data than are actually present in the file, processing the file may cause a buffer overflow in the Macromedia Flash plug-in.


The plug-in or browser may crash. Since this buffer is only read from, this overflow is unlikely to cause execution of malicious code.


While Macromedia did not produce a patch to correct this problem, it is possible that recent versions of the plug-in have corrected this problem.
