Microsoft re-released one of its Aug. 11 security updates, explaining that it had posted an incomplete version to its own download center last week. The admission was the third time in the past two months that Microsoft has had to re-issue a security-related update.
Users who manually downloaded MS08-051 since Aug. 12 to patch Office 2003 should obtain the second version as soon as possible, Microsoft said. People who obtained the update via Windows Update or through their company’s Windows Server Update Services (WSUS) server, or who updated other versions of Office, do not need to reinstall MS08-051.
That update patched three vulnerabilities in PowerPoint, the presentation maker included with Microsoft Office, including one that Microsoft labeled “critical,” its highest ranking. MS08-051 was one of 11 security bulletins released last week that patched 26 bugs, the most Microsoft has tackled in a single month for the last year and a half.
According to the revised bulletin published Thursday, the PowerPoint 2003 patches originally posted to Microsoft’s Download Center were the wrong versions. “While these versions did protect against the vulnerabilities discussed in the bulletin, they lacked other important security and reliability updates,” Microsoft said in the revamped MS08-051.
