On June 26, 2002, Microsoft released the original version of this bulletin, which described the patch it provided as being cumulative. We subsequently discovered that a file had been inadvertently omitted from the patch. While the omission had no effect on the effectiveness of the patch against the new vulnerabilities discussed below, it did mean that the patch was not cumulative. Specifically, the original patch did not include all of the fixes discussed in Microsoft Security Bulletin MS01-056. Microsoft have repackaged the patch to include the file and are re-releasing it to ensure that it truly is cumulative.
If you applied the patch delivered in Microsoft Security Bulletin MS01-056 and the one that was distributed with the original version of this bulletin, youre fully protected against all known vulnerabilities in Windows Media Player and dont need to take any action. Otherwise, we recommend that you apply the new version of the patch provided in MS02-032.
